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).
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.
