Timing Attack

Overview Affected versions of this package are vulnerable to Timing Attack in the ML-KEM Poly.toMsg, Poly.compressPoly, and PolyVec.compressPolyVec routines. An attacker can recover a long-term private key by sending ciphertexts and measuring the time taken by repeated decapsulation operations th...

However, several...

Sharks has a Bias of Polynomial Coefficients in Secret Sharing

Affected versions of this crate allowed for a bias when generating random polynomials for Shamir Secret Sharing, where instead of being within the range 0, 255 they were instead in the range 1, 255. A description from Cure53, who originally found the issue, is available: The correct method to...
