I recently found a security flaw in the Google Keyczar crypto library. The impact was that an attacker could forge signatures for data that was “signed” with the SHA-1 HMAC algorithm (the ...

Critical vulnerabilities exist in several JSON Web Token (JWT) libraries – namely the JavaScript and PHP versions – that could let an attacker bypass the verification step.

The HMAC hardware module allows performing NIST HMAC algorithms as standardized in the FIPS 198-1. The module is coupled with one of the NIST standard secure hash algorithm, SHA-1, SHA-256, ... The ...

For algorithm-intensive systems —including systems with communications, audio, video, imaging, and navigation functions— these delays and costs are exploding as system complexity increases. It ...
