cggmp21.rs/cggmp21/CHANGELOG.md

Changelog

v0.6.3

• Use paillier-zk v0.4.3 that has patched ZK proof which includes a missing check

Warning

This library version implements CGGMP21 which uses Zero-Knowledge proofs as defined the CGGMP21 paper, which contains a critical vulnerability that could lead to full private key recovery.

While we have patched this specific high-severity issue, ZK proofs still lacks other important security checks introduced in the revised CGGMP24 paper. The absence of these checks may expose other security risks.

For complete protection, please upgrade to the CGGMP24.
