Feedback Lunch: Deep Feedback Codes for Wiretap Channels

We consider reversely-degraded wiretap channels, for which the secrecy capacity is zero if there is no channel feedback. This work focuses on a seeded modular code design for the Gaussian wiretap channel with channel output feedback, combining universal hash functions for security and learned...

GHSA-7322-JRQ4-X5HF File reference keys leads to incorrect hashes on HMAC algorithms

Impact Users of HMAC-based algorithms HS256, HS384, and HS512 combined with Lcobucci\JWT\Signer\Key\LocalFileReference as key are having their tokens issued/validated using the file path as hashing key - instead of the contents. The HMAC hashing functions take any string as input and, since users...
