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) … [Read more...] about Single-Core CPU Cracked Post-Quantum Encryption Candidate Algorithm in Just an Hour

Post-Quantum TLS 1.3 and SSH Performance (preliminary results)
Co-author: Dimitrios Sikeridis. Motivation As brought up on multiple occasions, if a real-world quantum computer was ever built, it could jeopardize public key exchange, encryption, and digital signature schemes used in secure tunnel protocols today like (D)TLS, SSH, IKEv2/IPsec and more. To prepare for a post-quantum future, NIST has embarked on a journey of standardizing … [Read more...] about Post-Quantum TLS 1.3 and SSH Performance (preliminary results)
