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.

Brain drain affecting Israel could lead to severe economic difficulties
By BERNIE BELLAN (Oct. 27, 2026) As of the time of writing, the future shape of Israel’s Knesset was clear as mud. I always remember one of the most important lessons I learned as a Political Studies student, which is the structure-function relationship of any country’s political system, in which the structure of a country’s system of government determined how stable that country’s government was likely to be.
Are we lucky to be living in a parliamentary democracy – with a first past the post system of government, where it is not that complicated to cobble together a majority government – even if it means sometimes aligning with rival parties to form that majority?
After watching the spiral into authoritarianism now taking place in the U.S. under their fragmented democratic system where an unscrupulous president can appropriate almost unlimited power – unchecked by the toadies on the Supreme Court or members of Congress, I would say we’re so much luckier to be living within a parliamentary system of government.
But, when it comes to total disarray – no one can beat Israel’s system of government, where it is near impossible to put together a stable government unless – following the pattern of so many other formerly democratic countries, an authoritarian leader manages to assert himself and neutralize so many of that country’s democratic institutions – which is what we have seen happening under Netanyahu’s leadership.
I ask all these questions after having read an article on the Times of Israel website back in August, but whose relevance has become only more prominent as a result of Israel’s continual slide into disarray.
We in the West can pretend that Israel, for all its problems, is still a democracy, and that no matter what may be happening there, its citizens still want to live there.
But, after reading the TOI article, which was titled “Emigration of doctors, engineers, other highly educated Israelis hits record high,” one might be forgiven for thinking that Israel’s best and brightest are hurrying to leave their country.
Here are some figures from that story: A “Tel Aviv University report released earlier this week showed a record-setting trend of emigration from Israel continued in 2025, with nearly 50,000 Israelis leaving the country for the third year in a row.”
The article also noted that “High-earning Israelis working in tech and healthcare are emigrating in sharply rising numbers, almost doubling over five years, a new study by the Israel Tax Authority has found.
“The research by the Israel Tax Authority’s Planning and Economics Division, which examined incomes of Israeli emigrants over the past decade, found the rate at which affluent Israelis left the country increased sharply in 2023 and 2024 to record highs, and was almost double what it was until 2019.”
Although I posited that Israel’s political instability is a major reason for the exodus so so many high-income earners, the authors of the study say that it is not altogether clear what is behind the departure of so many talented Israelis: “The authors of the study stated that it was difficult to determine whether this shift in the makeup of emigrants stemmed from major changes that occurred in society and the labor market following the COVID-19 pandemic, or whether it was a reaction to the political upheaval over the judicial overhaul and security events that started with the October 7 onslaught and war in Gaza that have been shaking Israel since 2023.”
One might well ask whether a significant number of other Israelis would also leave the country, were they in an economic position to do so? After all, for many years, here in Manitoba we saw a large influx of Israelis, almost entirely coming from the middle class, who were drawn to come here by a combination of factors, including the GrowWinnipeg initiative – which made it attractive for young Israeli families to look to Winnipeg as a potential landing point, also the Provincial Nominee Program, which offered immigrants opportunities to find employment in areas where Manitoba was short of particular types of workers.
But, what of those high income Israelis to which the TOI article refers? Anecdotally, we have read and heard accounts of highly educated Israelis moving here (and Myron Love has often profiled some of those individuals), but if 150,000 Israelis have left the country, one wonders where they have all gone?
Here are the favourite destinations for Israelis looking to move somewhere else (in order): the U.S. Canada, United Kingdom, Cyprus, Portugal, Spain, Greece, Malta, Germany, Australia, and New Zealand.
Many of those countries have tightened their immigration rules, however, as the backlash in Western countries against immigrants from poorer countries has also led to an overall decrease in the number of immigrants allowed in from other Western countries, including Israel.
Still, for individuals with particular talents – or with very high incomes, finding a country to which they can move does not present the same problems as it would for people of lesser means.
Let me end this with this cautionary note from the TOI article: “For a country where the top 20% of income earners are paying 92% of all income tax revenue, the change in the mix of Israelis leaving the country represents a significant strategic risk to state revenues and growth in the economy.”
And, with so many countries now seeing Israel as a pariah state, with all the attendant economic consequences that portends, it is hard to be optimistic about Israel’s future.

Coincidence or not: Two books launched the same night – by my brother and by my niece
By GERRY POSNER Recently, on October 8, to be exact, an odd timing coincidence occurred in my family that struck me as highly unlikely. Two books were launched on the very same night in Toronto, at two separate locations. What was unusual for me was that one book was by my brother, Michael Posner and the other book was written by my niece, Elana Shira Segal. The topics, unsurprisingly, were not connected to each other. But you could not have planned that timing any worse than it turned out to be.

Michael Posner’s book, This Jewish Moment, an oral history of the Diaspora after October 7, 2023 had various people giving their opinions on a set of questions Michael posed to them as he interviewed them following the October 7, 2023 massacre. The interviews were conducted by Zoom. Each person interviewed was aware of the fact that the interview was recorded and that the interview might be used in a book. Each person’s name and age is given along with a brief description of who that person is. Some of the interviews were with people well known in Manitoba circles.The oral history technique is not new to Michael as he used it in the Leonard Cohen trilogies he created not that long ago and before that in his book on Mordecai Richler.
Michael interviewed over one hundred Jews in Canada and the United States. The thrust of the book was to explore how the events of October 7 affected the interviewees, how it changed (or didn’t change) their interpersonal relationships; altered, if at all, their spiritual lives; their trust in Jewish institutions and indeed, their perceptions about their own safety. It includes their thoughts about what lies ahead and even the idea of leaving North America. Without giving too much away, I can say that the opinions canvassed in the book do reflect a definite shift for many of the interviewees from their previous thoughts on these topics. If you read Michael’s book, you will not come away singing cheery songs. For many people, the future is bleak.
At the book launch held at the Beth Tikvah Synagogue in Toronto in front of about sixty people, there were several former Winnipeggers in attendance, including: Paul Shuckett, Bernie and Sheila Rubenstein, Aubrey Caplan and Philipa Glazerman, the former Susan Silverman, Gary Diamond, my son Ari Posner, and even a current resident of Winnipeg, Dolly Cohen, who came to visit her cousin Philipa.
Michael’s book, published by Sutherland Press, is in hardcover and ebook. It can be purchased at Indigo, and through Amazon.

Elana’s book is in an entirely different genre than her Uncle Michael’s book. Even the Darkness Has Stars is the title of her book -also her very first book. It is a work of fiction based on her career as a social worker and therapist for over 30 years in Toronto. The book explores the life of a teenage girl dealing not only with the usual teenage angst, but other issues as well. It is a book that will resonate with teenagers, and indeed parents of teenagers. It is a story of resilience and is an honest reflection of the very real problems facing many teens and ways to address their problems. I would suggest that the themes in the book are very relevant to teenagers today, especially girls. I think it is also fair to say that many parents of teenage children will identify with the difficulties faced by the chief protagonist in the book. Even counsellors and trained therapists will recognize the issues raised in this book. Schools and libraries would benefit from the book.
At her book launch, Elana outdrew her Uncle Michael as she had over one hundred people there. The conflict of the two books presented several of us in the family with an issue as to which event to attend. While my son Ari came to his uncle’s launch, his wife Tamar Kagan went to Ari’s first cousin Elana’s debut book launch. Even my wife and I split our allegiances.
Elana’s book can be ordered through Amazon or Barnes and Noble in the USA.


Now, if the oddity of the two books in the family being released at the same time was not enough, in November, another family member has a book coming out. This book is by my nephew Sam Posner’s wife, Erin Rothstein. Her book, called Watch Me is a guide to unlocking creative power. Erin is a visual artist, whose original paintings and limited edition prints have made her a name in the world of art already. She has a large following due to the success of her art. Her book deals with the ways to find your inner creativity and the ideas that spring to life when a person unlocks that creativity and gives him or herself permission to think bigger. If the book lives up to the art Erin creates, she will have a best seller. Erin’s book will be launched in four cities: Toronto, Montreal, New York and Los Angeles. It will be available at Indigo, Barnes and Noble, and through Amazon in hardcover, paperback, e-book and audiobook.
To the readers of this article, get out there and support the Posner family.

The late Dr. Maurice Shnider had a fascinating life – from serving in WWII to meeting famous celebrities who passed through Winnipeg

By MARTIN ZEILIG I first visited Dr. Maurice Shnider at his home in Winnipeg’s River Heights neighbourhood to talk about war.
His house reflected the life of a successful physician. It was spacious and comfortable without being ostentatious. Family photographs occupied shelves and tables. Sunlight spilled into the kitchen where we sat drinking coffee.
By then he was an elderly man, friendly, thoughtful, and possessed of that rare quality found in some people who have lived through extraordinary times. He never seemed impressed by his own experiences.
He had been born in Sheho, Saskatchewan, in 1923 and grew up in Inglis, Manitoba.
Then came the war.
As a young man he served with the Royal Canadian Air Force before being seconded to the Royal Air Force. Flying aboard Catalina flying boats in the Bay of Bengal, he participated in missions searching for downed Allied aircrew and earned the Distinguished Flying Cross.
Those were the stories I had come to hear and later wrote about for the Jewish Post & News.
Stories of long flights over open water.
Stories of rescue.
Stories of courage.
Yet as the interview continued, another chapter of his life emerged.
After the war he returned to Canada, attended medical school at the University of Manitoba, and eventually built a successful family practice in Winnipeg. His patients often became his friends. He took pride in caring for generations of families and became known as a gifted and dedicated physician.
For a period of years, he also served as the physician responsible for checking vaccination records and health documentation for international travellers passing through Winnipeg International Airport.
It was then that his eyes brightened.
The war stories were important.
The airport stories were fun.
“You’d be surprised who came through Winnipeg,” he said.
The coffee was fresh. Outside, a warm prairie breeze shifted the trees beyond the kitchen window.
Then he smiled.

“Even the Beatles.”
The name immediately caught my attention.
“The Beatles?”
He laughed.
“The whole city went crazy.”
It was August 18, 1964.
The Beatles were on their way to begin their first major North American tour and Winnipeg was merely a refuelling stop. They weren’t playing a concert. They weren’t staying overnight.
They were simply passing through.
Yet somehow word spread.
Radio stations reported it. Teenagers rushed to the airport. Parents drove excited daughters across the city. Traffic clogged nearby roads. The terminal filled with screaming fans hoping to catch a glimpse of the four young Englishmen who seemed to have conquered the world overnight.
Maurice happened to be the airport doctor assigned to examine the passengers’ health records.
What should have been a routine day suddenly became anything but.
Almost fifty years later, what remained vivid in his memory was not the famous faces but the sound.
The noise.
The shrieking.
The excitement.
For a brief moment Winnipeg became the centre of the universe for thousands of young Canadians.
Then the aircraft door opened.
John, Paul, George, and Ringo appeared.
They waved.
The crowd erupted.
A few photographs were taken.
A few words were exchanged.
And then, scarcely more than twenty minutes after they had arrived, they were gone.
Winnipeg returned to being Winnipeg.
Maurice chuckled at the memory.
“John Lennon was cheeky.”
I asked what he meant.
He considered the question.
“Always had a smart answer.”
He smiled again.
“Not rude. Just cheeky.”
The passage of decades had done nothing to diminish his amusement.
For a few moments we sat quietly.
Then another memory surfaced.

“Steve McQueen was one of the nicest.”
That surprised me.
Maurice encountered the actor in the airport restaurant.
McQueen was seated alone.
No entourage.
No photographers.
No one making a fuss.
Just a man eating lunch between flights.
Maurice rarely approached famous people.
But there was a reason that day.
One of his children was facing serious medical challenges and was a devoted Steve McQueen fan. Movies offered an escape from hospitals, treatments, and uncertainty.
So Maurice walked over to the actor’s table.
He introduced himself and explained the situation.
McQueen listened carefully.
Then he asked for the family’s address.
That was all.
No promises. No performance. No grand gesture.
Simply an address.
Several weeks later a package arrived at the Shnider home.
Inside was an autographed Steve McQueen poster.
Maurice’s expression softened as he recalled it.
The poster itself wasn’t what mattered.
What mattered was seeing the joy it brought.
Even years later, that was the part of the story he remembered most clearly.
“He was a very humble man,” Maurice said.
“Very soft-spoken.”
The kitchen fell silent.
For a moment the famous actor disappeared entirely from the story.
What remained was a father’s gratitude.
Then Maurice laughed again.

“Vanessa Redgrave.”
Another unexpected visitor.
She was travelling through Winnipeg on her way to Los Angeles when it was discovered that she lacked the proper vaccination documentation required for international travel.
In those days such requirements were taken seriously.
The problem needed solving.
So Maurice solved it.
He drove her downtown to his office.
One of the world’s most celebrated actresses riding through Winnipeg in a doctor’s car.
No limousine.
No security detail.
No red carpet.
Just traffic lights, city streets, and ordinary conversation.
There he administered the required vaccination and drove her back to the airport in time for her flight.
He told the story as though it were perfectly routine.
Perhaps for him it was.
I remember thinking that this was what made his stories so wonderful.
To everyone else they sounded extraordinary.
To Maurice they were simply things that had happened during a long and interesting life.
As our conversation drew to a close, he looked down into his coffee cup and reflected on the famous people who had crossed his path.
The Beatles.
Steve McQueen.
Vanessa Redgrave.
Different personalities.
Different kinds of fame.
Yet in the end they all became the same thing.
Travellers.
People worried about schedules.
People missing paperwork.
People trying to catch flights.
People trying to get somewhere.
The old airport had been a great equalizer. For a few moments, between arrival and departure, fame gave way to ordinary life.
And Maurice Shnider occupied a unique place in that world.
He wasn’t a celebrity.
He wasn’t an observer standing outside the story.
He was part of it.
A prairie boy who became a decorated wartime airman, flew rescue missions over distant seas, returned home to study medicine, built a respected family practice in Winnipeg, and devoted his life to helping others.
Some of the people he met happened to be famous.
Most were not.
To Maurice, it made little difference.
He especially enjoyed the company of pilots, storytellers, musicians, and adventurers. He remained fascinated by the Second World War, by history, and above all by people. Fame interested him far less than character.
He remembered the famous ones not because they were celebrities, but because, for a few brief moments, they revealed themselves to be something far more interesting.
Simply human.
When Dr. Maurice Shnider died in 2013 at the age of ninety, Winnipeg lost not only a distinguished physician and decorated veteran, but also a man who never lost his curiosity about the world or his affection for the people who passed through it.
Some departures are quickly forgotten.
Others leave a lasting mark.
That was how I remember him.
And that is how he deserves to be remembered.
