The Hacker News
A late-stage candidate encryption algorithm that was meant to withstand decryption by powerful quantum computers in the future has been trivially cracked by using a computer running Intel Xeon CPU in an hour's time. The algorithm in question is SIKE — short for Supersingular Isogeny Key Encapsulation — which made it to the fourth round of the Post-Quantum Cryptography (PQC) standardization
Bleeping Computer
Security researchers have discovered a new speculative execution attack called Retbleed that affects processors from both Intel and AMD and could be used to extract sensitive information. [...]
