A San Francisco company paid nearly $1 million for the solution to an unsolved code in Kryptos, a sculpture on the C.I.A.

Encryption systems rely on “random” numbers, but conventional computers can’t generate them perfectly. New research shows that quantum physics can.

Abstract: According to the research works of the literatures on chaotic cryptanalysis, many recent chaotic image encryption algorithms cannot resist chosen-plaintext attack. Although some chaotic ...

Just because you have antivirus software installed on your PC doesn't mean a zero-day Trojan can't steal your personal data. The top encryption software keeps you safe from malware (and the NSA). When ...

To mark World Privacy Day this year (28 January 2026), Index on Censorship invited extraordinary human rights activists to share their experiences of the importance ...

The day when quantum computers will be able to break conventional encryption is rapidly approaching, but not all companies are prepared to implement post-quantum cryptography. Quantum-safe encryption ...

Technology Computing Quantum Computing Quantum computing will make cryptography obsolete. But computer scientists are working to make them unhackable. When quantum computers become commonplace, ...

You’re at the checkout screen after an online shopping spree, ready to enter your credit card number. You type it in and instantly see a red error message ...

A new network paradigm can generate meaningfully random numbers—and fast. In network encryption, randomness has huge value because it’s not “solvable” by hackers. Classical computers can’t be ...

One day soon, at a research lab near Santa Barbara or Seattle or a secret facility in the Chinese mountains, it will begin: the sudden unlocking of the world’s secrets. Your secrets. Cybersecurity ...
