We will discuss secure methods of key sharing in a later article called “Cryptographic Algorithms.” The digest or hash that’s generated using a key is called an HMAC (Hash-based Message ...

HMAC supports any combination of SHA-2 algorithms, bit-length keys and messages. XTS-AES supports 128, 192 and 256-bit key sizes; whole block ciphering; and provides length-preserving encryption. The ...

Two researchers have improved a well-known technique for lattice basis reduction, opening up new avenues for practical experiments in cryptography and mathematics.

Cryptographic hashes are widely used in the secure communication protocols. "We updated our SHA family of cores to support an HMAC function inside the core," said Dmitri Varsanofiev, CTO of IP Cores. ...

* MD5-based HMAC algorithms will be disabled by default. In the just-released version 7.0, there are a number of cryptographic changes, as well.

Google announces new algorithm that makes FIDO encryption safe from quantum computers New approach combines ECDSA with post-quantum algorithm called Dilithium.

Peter Shor, a computer scientist at the Massachusetts Institute of Technology, explains why he devised an algorithm for a quantum computer that could unravel our online data encryption. Celeste ...
