World Quantum Day: The Most Important Security Problem No One Celebrates

QuintessenceLabs — Tue, 14 Apr 2026 13:00:04 GMT

The question isn’t when quantum will matter, but whether our cryptography can survive the transition.

From Policy to Protection: Why the Reauthorized National Quantum Initiative Matters Now

QuintessenceLabs — Thu, 15 Jan 2026 21:45:07 GMT

The recent bipartisan reauthorization of the U.S. National Quantum Initiative (NQI) is a strategic signal that the United States is moving decisively from quantum research to real-world readiness.

Why We Need Post-Quantum Cryptography (or Quantum-Safe Algorithms)

QuintessenceLabs — Mon, 25 Nov 2024 22:13:28 GMT

Most current encryption methods are computationally secure. While we know how to break them, the good news is that it would take a computer around 300 trillion years to break RSA-2048-bit encryption. So, we are good, right?

Well, perhaps we were, until Peter Shor discovered a new algorithm that would bring this down to around 10 seconds! The algorithm would however need a hypothetical device called a “Quantum Computer”. Such a device didn’t exist back then and still doesn’t exist today, but experts believe that a “cryptographic relevant quantum computer” (CRQC) will exist within the next decade.

This is why NIST started a project on upgrading vulnerable encryption methods back in 2015 and after working on this for more than eight years, they have just released three ﬁnalized standards:

Prepare Now for New NIST PQC Standards

New NIST Standards Are Only Months Away. Take Immediate Action to Secure Your Future with Post-Quantum Cryptography

Quantum security becomes a more tangible and critical concern in 2024. New post-quantum cryptographic (PQC) standards are expected in the new year from the U.S. Department of Commerce’s National Institute of Standards and Technology (NIST). We believe this pending release signals both the technological maturity of the solutions and the government’s acknowledgment of the severity of the quantum threat. It's only months away from the release of the standards and quantum readiness will not be a trivial undertaking. Here’s what you need to know as you plan for the migration to post-quantum cryptography.

The Spread of Quantum Resistance and Denial Disorder (QRDD)

QuintessenceLabs — Mon, 10 Apr 2023 16:36:26 GMT

More and more people in cybersecurity are being diagnosed every day with QRDD. In an informal poll of cybersecurity leaders and teams, respondents reported knowing at least one person displaying signs of Quantum Resistance and Denial Disorder (QRDD). So what is it and why is it such a cause for concern in the community?

Harvest Now, Decrypt Later? The Truth Behind This Common Quantum Theory

Is the Sky Really Falling?

To many, the term “quantum computing” equates to a world of new possibilities. What started as a theoretical curiosity is now touted as the future of IT. With quantum, there will be lightning fast processing of information and computers will be able to answer problems previously thought of as unsolvable.

Breaking RSA Encryption—Today

QuintessenceLabs — Thu, 19 Jan 2023 21:30:16 GMT

The Enigma Code, Zimmerman’s Telegram, the Copiale Cipher, and now … RSA? As with previously “uncrackable codes,” was the 46-year-old RSA public-key encryption system finally cracked? Chinese researchers have claimed their universal quantum algorithm based on Schnorr’s algorithm can reduce the quantum resources needed to break RSA encryption, presenting a near-term possibility that Quantum Computing will break RSA encryption.

Solving the Problem of Weak Encryption Keys

QuintessenceLabs — Thu, 20 Oct 2022 18:22:12 GMT

Over the past several decades, cryptography has evolved tremendously, yet breaches still occur, even in environments that were thought to be crypto secure. These exploitations have multiple causes, but weak encryption keys are one of the most pervasive factors. Fortunately, there are solutions to this problem. Let’s dive in.

Post-Quantum Cryptography – Four Ways to Address the Quantum Threat

In our last blog post, we discussed the underlying importance of entropy as cryptography advances in terms of requirements and capabilities. One of the most significant advances will be Post-Quantum Cryptography (PQC), and here we’ll discuss some facets of PQC that organizations need to understand.

Challenges to Common Criteria Certification Adoption

QuintessenceLabs — Wed, 20 Oct 2021 18:51:00 GMT

QuintessenceLabs is working with universities and government partners to understand Common Criteria adoption. The universities have compiled a survey to assist their research, and are looking to get as many inputs as possible to get a wide snapshot of industry opinion.
