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:

  1. Thermal Noise
  2. Semiconductor Quantum Physics
  3. Chaotic Oscillator Outputs
Generator TypeDescription
Thermal NoiseAmplifies and extracts random electrical noise from resistor thermal vibrations
Quantum PhysicsLeverages quantum mechanical properties like photon emission timing from LEDs/lasers
Chaotic CircuitsUses 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.

A daughter comes to terms with her father’s Holocaust experience many years later

author Bonny Reichert/cover of "How to Share an Egg"

“How to Share an Egg” by Bonny Reichert
Published by Appetite by Random House, 2025
Book Review by Julie Kirsh, former Sun Media News Research Director
Exclusive to The Jewish Post and News
Bonny Reichert writes with great compassion about her father, a Holocaust survivor. In reviewing children of survivor literature, much has been said about the need to compensate for the suffering of the Holocaust survivor. To upset parents after what they have been through, is to be avoided at all cost.
In my own survivor family, I learned that to ask questions of my parents about what happened during the war and even before the war was to cause pain. I learned not to ask, not to cause pain.
In 2015 Bonny Reichert and her family made a trip to Warsaw. The tomb of an ancestor called out to her father. The author’s great-grandfather was “a pillar of his community and a beloved scholar.” His namesake, the author’s father, was jubilant to find the headstone in the Warsaw cemetery. Afterwards the famished family found a deserted restaurant and revelled in a bowl of borscht garnished with fresh condiments. The description of this delicious meal is the reader’s introduction to the author’s moving memoir about food, love, hunger and survival. The author writes that in her family “food was connected to the meaning of life itself; an understanding woven into our very being.” The dining table was a very important place in the daily life of the family.
At age 5, the author noticed the blue-green numbers on her father’s arm. It was at this time that the father started to talk about his Holocaust experiences. By retelling his stories, the author’s father was reframing the horror into stories of bravery and triumph. In some ways, he was healing himself in the process of telling.
His daughter, the child of the survivor, tests her father’s Holocaust experience by putting a bare foot in the snow or trying to imagine unspeakable hunger. Trauma passed down the intergenerational chain has been explored in the children of the Holocaust survivors’ literature. Bonny Reichert absorbed her father’s trauma without understanding the origin of her own inherent sadness and dark feelings.
My high school years were spent going to movies, shopping and finding out about boys with my best friend, Linda. Her family, unlike my own, was a Canadian Jewish family who came to Toronto before the war. I considered Linda’s family normal and healthy. There were many aunts, uncles, cousins and even grandparents. Similarly, Cathy was the author’s best friend. In Cathy’s home there were no accents and no sad stories about tragedy and loss.
In her twenties, the author takes us through her engagement and marriage to the “right” guy. Turning down an opportunity to go to law school, staying at home with a baby, not dealing with depression was her life which she portrays poignantly in this memoir.
Most unexpectedly, she did not get the support that she needed from her father. He ignored her feelings. He saw her in the role of a traditional wife who had no outside aspirations other than to be a homemaker.
Therapy sessions helped her to take control of her life and become more aware of her authentic self. Her father was able to love her deeply and share the truths that he had learned through his Holocaust experience. However she came to understand that no one can define another person’s path. Taking journalism courses and having her voice published, helped the author’s sense of independence and self-esteem. In her late twenties, after divorcing her first husband, she married Michael, had two more children and balanced motherhood with her job as a magazine editor.
At age forty, the author enrolled in a culinary school. Conquering her unnamed fears, gave her an outlet for the energy trapped within. She learned that “being afraid is no way to live”.
In addition to exploring her personal psyche, the author writes about recreating lost recipes from before the war. The reader learns that Jews have been making cholent for many decades. Putterkuch or butter crumble cake was painstakingly recreated in her modern kitchen and taken to her father for his approval and insight into what he remembered about his mother and his childhood. Food became the trigger for buried memories.
In the final chapters of “How to Share an Egg,” the author goes on a fact finding mission to Berlin and Poland. She visited ghettos and concentration camps with a tour group.

Hedy Bohm is one of the Holocaust’s oldest survivors and was my mother’s best friend. She is the catalyst for persuading the author to conquer her lifelong fear of understanding the Holocaust survivor experience. At age eighty-four, she told her story in a German court of justice. For Hedy, this experience was validating, transforming her entire world view.
The author leaves us with food for thought. Fight the worst that history had to offer the Jews with beauty, happiness and continuation of life. Her father modelled resilience, courage and strength, allowing his daughter to choose her own response to life’s challenges.

Trump Wants to Incorporate Cryptocurrencies into the Strategic Reserve

President Trump intends for digital assets like Bitcoin, Ether, and a select group of other cryptocurrencies to eventually become part of the US strategic reserve. Although the exact process remains uncertain, market trends are already reflecting increased optimism beyond the US, drawing the attention of Canadian crypto adopters. Following Trump’s recent announcement, Bitcoin experienced its highest peak of a long time, a notable recovery from its previous drastic drop just days earlier.

These developments have sparked curiosity among Canadian investors, who could reshape market trends. In initial discussions in financial circles, experts pointed out that if the trend continues on an upward trajectory, this could spur the rise of innovations such as a number of new cryptocurrency. In this context, besides investing in the common Bitcoin and Ether, it would be worth considering investing in other cryptocurrencies. Exploring new cryptocurrency investment opportunities can be challenging, but experts claim that when approached wisely, it has the potential to be highly rewarding.

On Sunday, Trump disclosed for the first time the specific cryptocurrencies that could be integrated into a newly envisioned US crypto reserve. In a statement he posted on social media, he emphasized that leading digital currencies such as Bitcoin and Ether should form the core of this reserve, positioning them as essential elements in the nation’s future financial strategy. Following his announcement, President Trump not only emphasized Bitcoin but also identified other lesser-known cryptocurrencies – such as Ripple, Solana, and Cardano – as key components of his envisioned reserve. In his social media post, he declared, “I will make sure the U.S. is the Crypto Capital of the World.”

Crypto prices have rallied significantly after Trump’s announcement regarding the inclusion of Bitcoin and other digital currencies in strategic discussions. This announcement has sparked both excitement and skepticism among investors. Industry experts predict that these developments will drive broader institutional acceptance of cryptocurrencies across Canada. This could prove to be an influential factor in comprehensive regulatory reform and increased market stability.

Experts claim that, although vague, Trump’s promises give hope to investors worldwide. In the first few weeks of his presidency, the crypto sector did not receive the anticipated support. However, that initial disappointment seems to have transformed into renewed enthusiasm. Investopedia reports that by Monday morning, Bitcoin – after reaching a peak of about $109,000 in January and dropping last week on Trump’s announcement – had rebounded by over 8% to around $93,000. At the same time, Ether climbed roughly 7%, Solana increased by more than 13%, XRP surged over 16%, and Cardano jumped by over 50%.

Investopedia further reports that Bitcoin’s price encountered obstacles after it was confirmed that the Trump administration would proceed with its intended trade tariffs on Canada and Mexico. Investopedia further explains that investors often see tariffs as a driver of inflation. As a result, the expected interest reductions for the year of 2025 could be effectively offset, increasing pressure on volatile assets such as Bitcoin, which do not generate returns.

Investopedia notes that since 2013 Bitcoin has posted an equal number of gains and losses, making its performance hard to predict. Despite a roughly 5% drop in Bitcoin’s price since the beginning of 2025, Investopedia states that this cryptocurrency remains up approximately 25% compared to its level during the U.S. election period. This upward trend is largely driven by optimism that a Trump-led White House, along with a crypto-friendly Congress, will introduce policies that support the digital asset market.

Canadian crypto advocates see digital currencies as an opportunity to modernize everyday life. Local trading platforms are experiencing rising sales and an increase in user registrations. The recent fluctuations in cryptocurrencies have been accompanied by interest from strategic investors. Experts see the current developments as a potential turning point that could push digital financial solutions further into the spotlight for the public and politicians, which ultimately has long-term implications for Canada’s economic success. One sector that stands to gain significantly is Canada’s online gambling sector, a major contributor to the national economy.

Despite the current peak, financial experts warn of the risks. Cryptocurrencies are extremely volatile, especially when political and economic conditions change rapidly. Investment strategies must therefore adapt to a market that is both promising and unpredictable. Experts advise newcomers to invest cautiously and keep an eye on global trends. Such trends can have a lasting impact on the Canadian market.

Although the exact structure of future reserves remains unclear, the crypto-enthusiast President Trump has taken action by ordering the creation of a digital assets task force. This group is set to determine by July whether the US government should establish a strategic Bitcoin reserve. Investors are on edge, closely watching the potential ripple effects this development might have on the global trading market. Meanwhile, market observers expect further crypto-focused announcements from Trump in the coming days. The first crypto summit is scheduled to take place at the White House on Friday.

Leading Jewish poker players

From smoky bar-rooms in Texas to high-end casinos on the French Riviera, poker is booming across the world.

From underground games in China to Arctic villages where players bet with their ration supplies, the game has now spread across the planet’s different cultures, adapting to each one.

From online poker to a seat at an opulent casino table, the rules are simple but the strategy is deep… and that’s why it appeals to everyone.

How poker is conquering the world

In the US poker took off in the 19th century, spreading along the Mississippi River on gambling boats.

In China, variations like Dou Dizhu share poker’s competitive spirit. In Europe, poker thrives in plush casinos from London to Monaco.

Hollywood and TV have kept poker in the spotlight. From Casino Royale to Rain Man, big-screen showdowns have made the game even more glamorous.

The arrival of poker online games pushed the game even further. Today anyone with a phone can play against opponents worldwide.

Poker is about skill, risk and reading people. A strong hand isn’t always enough—you need nerve.

That’s why it remains an ultimate test of strategy and psychology. Whether played for pennies or millions, in dimly lit rooms or bright casinos, poker is a global game.

What type of player plays poker?

Poker appeals to no fixed type. Anyone can play.

Over the years, poker champions have come from every background. Old, young, rich, broke.

Men, women. Every nationality and every walk of life.

Doyle Brunson, the grizzled Texas road gambler, played through the Wild West days of poker and lived to write the book on it.

Johnny Chan, the Chinese-born master, dominated the 1980s, with his lucky orange always beside him.

Barbara Enright was the first woman to reach the WSOP Main Event final table. Vanessa Selbst, a Yale-educated lawyer, crushed high-stakes tournaments for years.

Online prodigies like Viktor ‘Isildur1’ Blom took on the world’s best from his computer screen.

From Arctic truckers playing in frozen outposts to Saudi businessmen gambling behind closed doors, poker appeals to every type.

It’s not about where you’re from or what you look like. It’s about how you play.

That’s why poker remains the most democratic and cosmopolitan game in the world.

The rise of Jewish Poker

Players from the Jewish community have always been a force in poker. The culture values sharp thinking, debate and strategy – perfect skills for the game.

For centuries, Jewish communities have embraced card games, from Eastern Europe to New York’s Lower East Side. The appeal is clear: poker rewards intellect over luck, skill over status.

That’s why some of the greatest players in history have been Jewish.

Take Erik Seidel. A quiet, calculating master, Seidel has nine WSOP bracelets and over $40 million in earnings.

He first made his mark in the 1988 WSOP Main Event, losing heads-up to Johnny Chan in a hand made famous by the movie Rounders. Seidel kept evolving, mastering live and online poker alike.

Stu Ungar was another legend. A fearless, aggressive genius who won three WSOP Main Events.

Ungar was raised in a tough New York neighborhood as a prodigy at gin rummy before switching to poker. His natural talent was stellar but his self-destructive lifestyle cut his career short.

Barry Greenstein, dubbed the ‘The Robin Hood of Poker,’ made millions in high-stakes cash games. Then donated much of his winnings to charity. Greenstein’s calm, disciplined style made him a feared opponent on poker tables everywhere.

Or how about Vanessa Selbst, the highest-earning female player in history? She was a fierce competitor with an aggressive style. Selbst dominated tournaments and made history by winning three WSOP bracelets in her career.

These players and many other success stories show how Jewish culture, with its love of wit, argument and mental agility, has always found a natural home at the poker table.

Poker can be played by everyone

Jewish players like these have left a deep mark on poker.

The game rewards intelligence, strategy, and psychological insight – traits valued in Jewish culture. From Erik Seidel’s quiet precision to Stu Ungar’s raw talent, players from the community have shaped the game at every level.

Whether in smoky backrooms or high-stakes tournaments, they’ve benefited from their sharp minds and fearless play.

But poker belongs to no single group. It thrives in every culture.

In China, card games with poker-like strategy have existed for centuries. In Russia, cold, calculated players dominate the online scene.

In Brazil, an energetic new poker generation is making waves. From Arctic villages to African casinos, the game is adapting to the modern world.

Poker’s appeal is universal. It’s not about where you’re from, but how you play.

Bluffing, reading opponents, taking risks – these are human instincts.

That’s why poker will remain the world’s greatest card game. It speaks a language that everyone understands.
