Cryptographic doom principle
WebCryptographic Doom Principle (CDP) Applied to SSL/TLS Notes: 1. Padding may have to be added to the last block of plaintext 2. Value of each pad byte is the number of bytes being added so it is easy to check that padding is not valid IV WebAug 1, 2024 · Quite a few cryptographic algorithms ask a user to provide a curve point and, by design, assume the point is valid and the equation holds. 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.
