Scientists are probing the eerie world of quantum physics in a quest to develop the elusive wonder weapon of espionage — an uncrackable code. The potential commercial and military application… ...

While efforts in Europe focused on Enigma, the outcome of the Pacific War hinged on intercepting and breaking Japanese naval ciphers—most notably the code known as JN-25. This code was a two-step ...

If someone develops a supercomputer that is twice as fast, a code user need only start using 129-bit encryption to maintain the same relative advantage.

Code-based cryptography is a promising branch of post-quantum cryptography that exploits the inherent complexity of decoding linear error-correcting codes. Traditional schemes, such as the ...

This was the state of substitution cryptography before the advent of complex calculating machines. Soon, mechanical developments would make this sort of code look like child's play.

Here’s another big question: Even if the answer to that last question is no, could quantum computers in some other way wind up empowering code makers as much as code breakers?

ANNAPOLIS, Md., January 07, 2025--X9 has published a new standard, X9.148, that specifies the use of cryptography to protect QR Codes.
