Known Vulnerabilities
- Lattice reduction (non-standardized parameter sets)
Notes
Original NTRU submissions used non-standardized parameters. The underlying lattice problem may be quantum-resistant, but without NIST standardization and rigorous parameter selection, it is classified as unsafe. Use NIST-standardized ML-KEM instead.
