Known vulnerabilities

Issue Description Mitigation
Side-channel leakage Table-based AES leaks key-dependent timing information on shared hardware. Use constant-time primitives or dedicated CPU instructions when side-channels matter.
Mode misuse Reusing IVs or operating without authentication enables practical attacks despite strong core primitive. Pair AES with authenticated modes (GCM, CCM) and fresh IVs for each message.
