Vital Role of True Randomness in Modern Computing
The critical need for true randomness in cryptography, simulations, and more
True randomness is essential for encryption, statistical sampling, simulations, and more computing applications to work effectively. We explore why.
The concept of randomness often evokes thoughts of unpredictability and chance occurrences. However in the world of computing, having access to true randomness is vital for many critical applications to function properly. Without the ability to generate random values and data, key aspects of modern technology simply would not work reliably.
In this article, we will explore what constitutes true randomness from a computational perspective, why it is crucially important, and some of the ways that software and hardware attempt to produce randomness reliably. Gaining insight into this topic highlights the dependence much of digital functionality has on the availability of non-deterministic, uniformly distributed random data.
What Makes Randomness “True”?
For data to be considered truly random from an information theory perspective, values must satisfy key mathematical and statistical qualities, for example at Lucky Seven Casino. True randomness implies meeting three core criteria:
- Uniform distribution — All potential values have an equal probability of occurring so that no bias exists towards certain numbers.
- Independence — The value at any position does not relate to or depends on values at other positions. Previous numbers do not influence future ones.
- Unpredictability — Knowing some values provides no useful information to predict other values. Guessing upcoming numbers is mathematically impossible.
Hence, true randomness requires generated data featuring high entropy (information density) with no observable patterns or correlations over any length or time period analyzed. Values must pass various statisticatests of randomness to qualify. True randomness exists only in specific natural phenomena scientists believe exhibit fundamental uncertainty such as radioactive decay. Computational methods can attempt to produce randomness but technically generate only an approximation usually called pseudo-randomness. However for many practical purposes, computationally generated randomness proves sufficient if it passes robust statistical testing.
Why True Randomness Matters Cryptography
Arguably, the area with the most crucial dependence on true randomness is cryptography. All modern encryption technologies require random number generation to ensure security. Encryption systems work by utilizing random numbers for:
- Key generation
- Initialization vectors
- Salts
- Nonces
- Padding
Any bias, predictability or correlation within random values used for the above purposes significantly compromises encryption protocols and introduces vulnerabilities. With trillions of dollars transferred online daily and vast amounts of sensitive data stored digitally, safeguarding cryptography requires high-quality random number generation rooted in solid entropy sources.
Simulations & Modeling
Outside of security, many more computing applications need randomness to operate correctly per their design intent. Monte Carlo simulations extensively utilize randomness to model complex real-world behaviors by running many iterations with differing random inputs. Financial analysis, climate modeling, nuclear reactions and molecular behavior represent common Monte Carlo simulation applications.
Games, Artificial Intelligence & Machine Learning
Gaming, AI and ML commonly incorporate randomness to increase variation, introduce unpredictability, and improve realism. For example, non-player characters in video games use randomness for movement, dialog and behavior to feel more lifelike and less robotic. AI/ML leverage randomness to train networks more thoroughly against a wider possibility space and build more resilient models less prone to biases.
Generating True Randomness via Hardware
Given the pervasive need for genuine randomness across computing, how do software and hardware reliably produce it? Most systems today use either specialized hardware random number generators or hybrid combinations of hardware and software.
Hardware options utilize the inherent randomness within low-level physical phenomena to produce entropy. Different techniques for generating randomness exist but most hardware implementations focus on three main sources:
- Thermal Noise
- Semiconductor Quantum Physics
- Chaotic Oscillator Outputs
Generator Type | Description |
Thermal Noise | Amplifies and extracts random electrical noise from resistor thermal vibrations |
Quantum Physics | Leverages quantum mechanical properties like photon emission timing from LEDs/lasers |
Chaotic Circuits | Uses unpredictable oscillator circuit outputs from chaos theory |
Semiconductor-based solutions can generate high bitrates up to 5Gbps using compact modern chip fabrication allowing extensive harvestingof entropy. However these sources derive from complex, random physical processes proving impossible to predict or fully model mathematically. This unpredictability provides excellent entropy quality unattainable via software algorithms alone.
Most general-purpose computers now integrate random number generators within CPUs allowing applications access to decent hardware-based random data. For the highest security use cases, dedicated standalone hardware random number generators exist exceeding >100Gbps speeds. Hence accessing genuine randomness is available today even on common computing devices.
Cryptographically Secure Pseudo-Random Number Generators
While hardware mechanisms utilize hard-to-predict physical phenomena to produce randomness, software solutions must take a different approach. Algorithmically-generated randomness cannot achieve true randomness from a physics perspective. However clever mathematical techniques like cyclical algorithms can generate randomness passing many statistical tests of randomness within their output bit length limits.
Cryptographically secure pseudo-random number generators (CSPRNG) serve as the premier software-based method for generating randomness. CSPRNGs work by repeatedly applying cryptographic primitives like hash or cipher functions on initial random seed values. This process produces a chain of output bits not reproducible without the original seed key. Leading CSPRNG algorithms include:
- Hash_DRBG
- HMAC_DRBG
- CTR_DRBG
Software libraries implement these CSPRNGs so developers can integrate quality randomness into applications with proper seeding. Seeding establishes the initial starting point for randomness generation using an entropy source like hardware random number generators or timing variability.
CSPRNGs allow the production of vast quantities of randomized data for any purpose needed. Compared to hardware mechanisms limited by physics on maximum speeds, algorithms scale boundlessly in the bits created as long as adequate computational power exists.
Yet key differences between software and hardware randomness remain. While CSPRNG outputs pass statistical testing and contain no observable patterns, their pseudo-randomness means given the same seed, the exact same value sequence will generate each time. Also, if a CSPRNG algorithm or implementation has flaws, adversaries could predict and exploit output resulting in compromised security. Still, with proper cryptographic design and regular reseeding, CSPRNGs provide quality randomness for most software needs.
Conclusion
From the above exploration, we see true randomness plays a pivotal role across computing – from cybersecurity to simulations and beyond. While no substitutes for true physically-derived entropy exist, modern hardware and hybrid hardware-software solutions provide abundant randomness for practical usage.
However as computing continues evolving with new technologies like quantum, ensuring high-quality randomness generation tackles emerging information security and system reliability challenges. Access to ample true randomness stands necessary now for current computing functionality and lays the foundation for future innovation.

Antisemitism in the Medical Profession in Canada

By HENRY SREBRNIK (June 27, 2025) Antisemitism in Canada now flourishes even where few would expect to confront it. Since the Hamas attack on Israel on October 7, 2023, there has been a resurgence of antisemitism noticeable in the world of healthcare.
When Israeli Gill Kazevman applied to medical school, and circulated his CV to physician mentors, their most consistent feedback was, “Do not mention anything relating to Israel,” he told National Post journalist Sharon Kirkey in an Aug. 10, 2024, story. As a student at the University of Toronto’s Temerty Faculty of Medicine, “I began to see all kinds of caricatures against Jews. I saw faculty members, people in power, people that I’m supposed to rely on, post horrible things against Jews, against Israelis,” he added. The faculty created a Senior Advisor on Antisemitism, Dr. Ayelet Kuper, who in a report released in 2022, confirmed widespread anti-Jewish hatred.
The Jewish Medical Association of Ontario (JMAO) conducted a 2024 survey of 944 Jewish doctors and medical students from across Canada. Two thirds of respondents were “concerned that antisemitic bias from peers or educators will negatively affect their careers.” Dr. Lisa Salomon, JMAO’s president, reported that at the University of Toronto medical school only 11 Jewish students were completing their first year of medical school out of a class of 291. The medical school in 1974 saw 46 Jews in a class of 218.
Also in Toronto, Hillel Ontario called on Toronto Metropolitan University to investigate Dr. Maher El-Masri, who has served as the director of the Daphne Cockwell School of Nursing, because, the group contended, he has “repeatedly engaged with and spread extreme, antisemitic, and deeply polarizing content on his social media account.”
The National Post’s Ari Blaff in an article on June 12, 2025 quoted social media posts from an account Hillel claimed belongs to Dr. Maher El-Masri, who has been the director of the Daphne Cockwell School of Nursing. One message concerned a post about Noa Marciano, an Israeli intelligence soldier abducted by Hamas on Oct. 7, 2023, who later died in captivity. “This is what is so scary about people like her,” the TMU professor wrote. “They look so normal and innocent, but they hide monstrous killers in their sick, brainwashed minds.” Israel, he asserted a day after the Hillel notice, “is a baby killer state. It always has been.”
The Quebec Jewish Physicians Association (AMJQ) is fighting antisemitism in that province. Montreal cardiologist Dr. Lior Bibas, who also teaches at Université de Montréal, co-founded the group in the weeks following the October 7 terrorist attack. They feel young doctors have been bearing the brunt of anti-Israel sentiment since then. “We heard that trainees were having a hard time,” he told Joel Ceausu of the Canadian Jewish News Feb. 3. “We saw a worsening of the situation and were hearing stories of trainees removed from study groups, others put on the defensive about what’s happening,” and some saw relationships with residents deteriorating very quickly.
Dr. Bibas thinks there are similarities with Ontario counterparts. “Trainees are getting the brunt of all this. Their entire training ecosystem — relationships with peers and physicians — has changed.” Whether anti-Zionist remarks, blaming Jews for Israel’s actions, or other behaviour, it can be debilitating in a grueling academic and career setting. The fear of retaliation is so strong, that some students were unwilling to report incidents, even anonymously.
Jewish physicians have now founded a national umbrella group, the Canadian Federation of Jewish Medical Associations (CFJMA), linking the provinces, and representing over 2,000 Jewish physicians and medical learners, advocating for their interests and promoting culturally safe care for Jewish patients. And “it’s really been nonstop, given that we have a lot of issues,” Dr. Bibas told me in a conversation June 17. “People have been feeling that there’s been a weaponization of health care against Israel.”
He stressed that health care should remain politically neutral – meetings are an inappropriate venue in which to talk about the war in Gaza, he stated, and “this will just lead to arguments.” Nor should doctors, nurses and hospital staff wear pins with Palestinian maps or flags. And no Jewish patient being wheeled into an operating room should see this “symbol of hate.”
On Jan. 6, a group of Montreal-area medical professionals walked off the job to protest outside Radio-Canada offices, calling for an arms embargo, ceasefire and medical boycotts of Israel. Those who could not attend were encouraged to wear pins and keffiyehs to work. When asked if such a walkout should be sanctioned, Quebec Health Minister Christian Dubé’s office had no comment. Neither did the Collège des médecins (CDM) that governs professional responsibilities. The leadership of many institutions have remained passive.
B’nai Brith Canada recently exposed a group channel, hosted on the social media platform Discord, in which Quebec students engaged in antisemitic, racist, misogynistic and homophobic rhetoric. More than 1,400 applicants to Quebec medical schools, as well as currently enrolled medical school students, were in the group, which was ostensibly set up to support students preparing for admission to Quebec’s four medical programs. “I saw it, and it’s vile,” remarked Dr. Bibas, noting how brazenly some of the commentators expressed themselves, using Islamist rhetoric and Nazi-era imagery, such as referring to Anne Frank as “the rat in the attic.”
Doctors Against Racism and Antisemitism (DARA) said in a statement, “These messages are the direct result of the inaction and prolonged silence of medical school and university leaders across Canada since October 7, 2023, in the face of the meteoric rise of antisemitism in their institutions. Silence is no longer an option. Quebec’s medical schools and universities must act immediately. These candidates must not be admitted to medical school.” DARA member Dr. Philip Berger stated that “there’s been a free flow, really, an avalanche of anti-Israel propaganda, relentlessly sliding into Canadian medical faculties and on university campuses.”
In Winnipeg, a valedictory speech delivered to the 2024 class of medical school students graduating from the Max Rady College of Medicine at the University of Manitoba on May 16, 2024 set off a storm of controversy, as reported by Bernie Bellan in this newspaper. It involved a strongly worded criticism of Israel by Dr. Gem Newman. “I call on my fellow graduates to oppose injustice -and violence — individual and systemic” in Palestine, “where Israel’s deliberate targeting of hospitals and other civilian infrastructure has led to more than 35,000 deaths and widespread famine and disease.” The newspaper noted that “loud cheers erupted at that point from among the students.”
The next day, the dean of the college, Dr. Peter Nickerson, issued a strongly worded criticism of Dr. Newman’s remarks. On Monday, May 20, Ernest Rady, who made a donation of $30 million to the University of Manitoba in 2016, and whose father, Max Rady, now has his name on the school, sent an email in response to Dr. Newman’s remarks.
“I write to you today because I was both hurt and appalled by the remarks the valedictorian, Gem Newman, gave at last week’s Max Rady College of Medicine convocation, and I was extremely disappointed in the University’s inadequate response. Newman’s speech not only dishonored the memory of my father, but also disrespected and disparaged Jewish people as a whole, including the Jewish students who were in attendance at that convocation.”
In subsequent weeks Jewish physicians in Manitoba organized themselves into a new group, “The Jewish Physicians of Manitoba.” As Dr. Michael Boroditsky, who was then President of Doctors Manitoba, noted, “Jewish physicians in cities across Canada and the U.S. have been forming formal associations in response to heightened antisemitism following the Hamas massacre of October 7.”
After October 7, Jewish students at the University of Calgary’s Cumming School of Medicine reported exposure to repeated antisemitic posts by peers on social media, being subject to antisemitic presentations endorsed by faculty during mandatory classes, social exclusion and hateful targeting by university-funded student groups, and removal from learning environments or opportunities subsequent to antisemitic tirades made by faculty in public spaces.
In addition to online vitriol, medical students have been subject to antisemitic actions coordinated by university-funded student groups with physician-faculty support under the guise of advocating against the actions of the Israeli government. All instances of discrimination, they stated in a brief, have been witnessed by and/or reported to senior leadership of the medical school without incurring condemnation of the discrimination.
In Vancouver, social media posts vilifying Israel and espousing Jew hatred were circulated by physicians at the Faculty of Medicine of the University of British Columbia, noted an article in the National Post of May 25, 2025. Allegations included Christ-killing, organ trafficking, and other nefarious conspiracies supposedly hatched by Jewish doctors. Some asserted that Jewish faculty should not be allowed to adjudicate resident matching because the examining doctors were Jewish and might be racist.
In November of 2023, one-third of all UBC medical students signed a petition endorsing this call. Jewish learners who refused to sign were harassed by staff and students on social media. When challenged, the Dean of the medical faculty refused to recognize antisemitism as a problem at UBC or to meet with the representatives of almost 300 Jewish physicians who had signed a letter expressing concern about the tolerance of Jew hatred, and the danger of a toxic hyper-politicized academic environment. This led to the public resignation of Dr. Ted Rosenberg, a senior Jewish faculty member.
Here in the Maritimes, things seem less dire. I spoke to Dr. Ian Epstein, a faculty member in the Division of Digestive Care & Endoscopy at the Dalhousie University Faculty of Medicine. He helps coordinate a group supporting Jewish and Israeli faculty, residents and medical students.
“Our group is certainly aware of growing antisemitism. Many are hiding their Jewish identities. There have been instances resulting in Jewish and Israeli students being excluded and becoming isolated. It has been hard to have non-Jewish colleagues understand. That said our group has come together when needed, and we have not faced some of the same challenges as larger centres,” Dr. Epstein told me. Dalhousie has also taken a stand against academic boycotts of Israel, which some view as a form of antisemitism. The University of Prince Edward Island in Charlottetown has just opened a new medical school. Let’s hope this doesn’t happen here.
Lior Bibas in Montreal indicated that his group is worried “not only as Jewish doctors and professionals, but for Jewish patients who are more than ever concerned with who they’re meeting.” Can we really conceive of a future where you’re not sure if “the doctor will hate you now?”

I Speak “Jew”

By MARK E. PAULL I grew up in Montreal. Born in 1956. Anglo by birth, sure. But that never quite fit. I don’t speak “Anglo” the way they mean it. My real language is Jew.
And I don’t mean Hebrew or Yiddish. I mean the language of reading the room before you enter it. The code-switching, shame-dodging, laugh-first-so-they-don’t-pounce dialect we pick up early. It’s a language built on side-eyes and timing and ten generations of tension.
I speak French—enough to make myself understood. Enough to charm a dinner table, crack a joke, get someone’s uncle to nod. I’m not fluent, but I’m fast. Doesn’t matter. In Quebec, language isn’t grammar—it’s inheritance. It’s who your grandfather cursed out in a hardware store.
To the Francophones, I’ll never be one of them. My accent betrays me before I say a word. I’m just an Anglo. And not even that, really. Because when the lens tightens, when they look closely, I’m just un Juif. Just a Jew.
And to the Anglos? Same thing. I can wear the suit, speak the Queen’s English, order the wine properly—still a Jew. Even in rooms where I “pass,” I don’t belong. I’m not invited in to be myself. I’m invited in to behave. To be safe. To not say the thing that makes the air stiff.
We’re the only people still called by our religion. No one says “Orthodox” for a Greek. No one says “Vatican” for an Italian. No one calls a Black man “Baptist” before they see his face. But “Jew”? That sticks. That’s the label. Before passport. Before language. Before hello.
I’ve mostly made peace with that. But there’s still this ache—knowing you can live your whole life in a place and never really be from there.
Let me tell you a story.
We had this block party once—the folding-table, paper-plate kind. Kids zipping by on scooters. Music low. Everyone asked to bring something from “your culture.”
The Greek guy brought lemon potatoes and lamb—felt like it came with a side of Byzantine history. The Italians brought two lasagnas—meat and veggie—with basil placed like confetti. The Vietnamese couple brought shrimp rolls that vanished before they hit the table. Even the German guy—built like a fridge—brought bratwurst and a six-pack with gothic lettering.
And then us.
My partner made Moroccan fish. Her grandmother’s recipe. Red with tomatoes, garlic, cumin. Studded with olives and preserved lemon. I brought a bottle of white wine. Dry. Crisp. From the Golan Heights. Not Manischewitz. Not even close.
We laid it out. Someone leaned over: “Moroccan? But I thought you were Jewish.”
We smiled. “We are.”
Then: “So… where’s the brisket? Isn’t Jewish wine supposed to be sweet?”
That’s when it hits you. No matter how long you’ve lived here, how many snowstorms you’ve shoveled through, you’re still explaining yourself. Still translating your presence.
Because they don’t know. They don’t know Jews came from everywhere. That “Jewish” isn’t one dish—it’s a whole map. That we had Jews in Morocco before there was even a France. That some of us grew up on kreplach, some on kefta. That some of our mothers sang in Yiddish, others in Arabic, and some in both—depending on who was knocking.
They don’t know. And worse—they don’t ask.
And that’s the part that gets you. Not the slurs. Not the graffiti. Not even the occasional muttered cliché. It’s the blankness. The shrug. The image they already have of you that’s built out of dreidels and sitcoms.
“Jewish” as nostalgic. As novelty. Something they saw once on a bagel.
Sometimes, when those questions come, I float. One version of me walks out. Another turns into a mouse. One turns into a Frisbee. Just gone. Not mad. Just tired.
Because being a Jew isn’t cute. It’s not nostalgic.
It’s ancient.
Before Montreal.
Before France.
Before Poland. Before Spain.
Before pogroms.
Before ghettos.
Before Hitler.
Before even the word Europe.
We were there.
Go back to the 5th century. 2nd century.
Go back to Jesus—our kid, by the way.
Go further—Babylon. Persia.
Keep going—Temple. Exile. Wandering.
And still, after all that, I’m at a table in Quebec explaining why our fish has cumin in it.
It’s almost funny. If it didn’t wear you down a little.
I’m not looking for pity. This isn’t a complaint.
I’m proud. I know what I carry. I walk into any room with five thousand years behind me. I come from people who kept the lights on through every kind of darkness—and laughed through it, too.
But sometimes, I just wish I didn’t have to explain so much.
All I want is to put down my dish…
…and hear someone say:
“That smells amazing. Tell me the story.”
That’s all.

At 104, Besse Gurevich last original resident of Shaftesbury Park Retirement Residence

By MYRON LOVE At 104, Besse Gurevich is the last of the original residents of Shaftesbury Park Retirement Residence. She may also be the oldest member of our Jewish community.
Although her vision and her hearing have diminished considerably, her mind and memory are still intact. A few weeks back, this writer sat down with her in her suite as she recalled a life filled with highs and lows and her many contributions to her community, both in Winnipeg and Fort William before that.
The daughter of Jack and Rebecca Avit, her life’s journey began in 1921 in a home on Carlton Street near Ellice Avenue, near her father’s furniture store. He later operated a cap factory.
When she was ten, the family – she had two brothers and a sister – moved to Manitoba Avenue in the old North End. “My father had put a deposit down on a house on Scotia,” she recalls. “But my parents didn’t feel that the neighbourhood was Jewish enough.”
Her schooling included Peretz School and, like so many of her generation, St. John’s Tech (as it was known back then.) “I was actually supposed to be going to Isaac Newton for high school,” she says. We were living on the wrong side of the tracks for St. John’s. After one day at Isaac Newton, I found a way to transfer to St. John’s.”
In 1940, 19-year-old Bessie Avit married Jack Gurevich, a young man from Fort William. The wedding was marred though, by the sudden, untimely passing of her father.
Following the wedding, Besse moved with her new husband to Fort William where Jack Gurevich worked in retail clothing sales. “We lived in Fort William for 20 years,” she says. “Our three children (Judy, Richard and Howard) were born there.”
She recalls that there were about 200 Jewish families – including her sister and one of her brothers for some years – in town, during the time she lived there. “We were very well known in the community,” she recalls. “I was involved in everything.”
Her community activism continued after the family’s return to her home town. While Jack went to work as a salesman for Western Glove Works, Besse became an indefatigable community volunteer. At one time or another, she served as vice-president of ORT, Hadassah and National Council of Jewish Women in Winnipeg. She was also a long time B’nai Brith member.
In the business world, the highlight of her career was the building of Linden Woods. “I became involved in real estate development for a time,” she recalls. “I was hired by Genstar to develop Linden Woods. The company estimated that it would take about 20 years to complete. I got it done in two.”
She also taught hair dressing for a while. “I worked with many young Jewish brides,” she says.
Recent years have not been kind to Besse Gurevich. Her beloved husband, Jack, died in 2016 – after almost 65 years of marriage. Older son, Richard, passed away in Vancouver in 2018 and, most recently –six months ago – younger son, Howard, followed. She notes that there were 200 mourners at Howard’s funeral.
(Howard Gurevich was in marketing for many years before turning his talents to the art world. In recent years, he was best known for Gurevich Fine Art in the Exchange District and his support of local artists.)
Besse Gurevich celebrated her 100th birthday – which took place at the height of the Covid shutdown – quietly.
While she used to enjoy reading. she is unable to do so any more. She can still listen to television.
And while she has few family members to visit her any more, she does have a group of friends interesting enough from the local theatre scene. For many years, she was a close friend of the late Doreen Brownstone, one of the leading figures in theatre in Winnipeg for more than half a century. Besse became part of the group that would visit Doreen every week and, since Doreen passed on three years ago, the members of the group have continued to visit Besse on a weekly basis.
