Cryptographic doom principle

WebIf you have to perform any cryptographic operation before verifying the MAC on a message you’ve received, it will somehow inevitably lead to doom. GCM, for instance, does not violate this principle, so it is vastly preferred. RSA on the other hand does not support forward secrecy, which is a VERY useful feature when it comes to cryptography.

WebMay 4, 2016 · If they do, we call that a padding oracle, and a MitM can use it to learn the value of the last byte of any block, and by iteration often the entire message. In other words, the CBC mode cipher suites are doomed by The Cryptographic Doom Principle. WebAug 1, 2024 · Failing to verify that received curve points are on the curve before doing math with them isn’t too far from violating the cryptographic doom principle and has similar consequences. In elliptic curve schemes, the secret is usually a regular number (remember, finding n such that Q = n * P is the hard problem).
