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

Code-based cryptography employs error-correcting codes as the basis for secure public-key schemes, leveraging the intrinsic difficulty of decoding a random linear ...

I dont know what other forum to put this on...sooo. ;P <P>I remember reading a while back about some code book that had a bunch of cryptography puzzles in it. Like a puzzle book, i guess. <P>I wanted ...

Quantum computers powerful enough to break widely used public-key encryption aren’t here yet, but migration won’t be as simple as swapping in a new tool.

Quantum computing presents both a potential breakthrough and a cryptographic threat -- one that Microsoft is tackling through what it calls "progress towards next‑generation cryptography." In a post ...
