A formula used to turn ordinary data, or "plaintext," into a secret coded message known as "ciphertext." The ciphertext can reside in storage or travel over unsecure networks without its contents ...

Quantum computers can't crack regular VPN encryption just yet, but what happens when that changes?

In 1994, a Bell Labs mathematician named Peter Shor cooked up an algorithm with frightening potential. By vastly reducing the computing resources required to factor large numbers—to break them down ...

It’s proven that today’s encryption is vulnerable to attack by a sufficiently mature quantum computer running Shor’s algorithm - a catastrophic event commonly known as Q-Day. Even before such a ...

Mathematics has always been at the core of securing information. From online banking to government communications, modern ...

Update: On 18 April, Yilei Chen announced an issue with his algorithm which he does not know how to fix. This means the algorithm does not undermine the mathematics behind post-quantum cryptography.

Every message, financial transaction, medical record, or government document encrypted today could remain stored ...

The US Department of Commerce's technical standards organization NIST has nominated the Ascon group of cryptographic algorithms for protecting small devices and information transmitted to and from IoT ...

The announcement follows a six-year effort to devise and then vet encryption methods to significantly increase the security of digital information, the agency said. The Department of Commerce’s ...

Krishi specializes in making complex tech topics, like VPNs, cybersecurity, and online privacy, clear and accessible. With 5+ years of writing experience, his work appears in outlets such as TechRadar ...

Post-quantum cryptography is moving from a future security concern to a practical planning issue for organizations. Quantum computers powerful enough to break widely used public-key encryption aren’t ...
