Security Cryptography WhateverPost-Quantum iMessage with Douglas StebilaApple iMessage is getting a big upgrade! Not only are they rolling out ratcheting, but they’re going post-quantum, AND they’re doing post-quantum ratcheting! Douglas Stebila joined us to talk about his security analysis of the new PQ3 protocol update and not indulge our wild Apple speculations:Transcript: https://securitycryptographywhatever.com/2024/03/03/post-quantum-imessage-with-douglas-stebila/Links:- https://security.apple.com/blog/imessage-pq3/- Security analysis of the iMessage PQ3 protocolhttps://security.apple.com/assets/files/A_Formal_Analysis_of_the_iMessage_PQ3_Messaging_Protocol_Basin_et_al.pdf- Ratcheting design: http...2024-03-0355 min
Cryptography FMEpisode 1: Post-Quantum TLS With KEMs Instead of Signatures!TLS 1.3 has been widely praised as a major upgrade to the Transport Layer Security protocol responsible for securing the majority of Web traffic. But one area in which TLS 1.3 seems to be lacking is its potential for resistance to attacks that utilize quantum computing – computers that, theoretically, could factor the products of large primes and solve the discrete logarithm problem in relatively short periods of time, significantly affecting the security of TLS 1.3.
Today however, we’re discussing an interesting new paper, to be published at this year’s ACM CCS, which introduces KEMTLS: a modified version of TLS 1...2020-09-2935 min
