A method is proposed to reduce ML-KEM-768 public key sizes by 24 octets by compressing polynomial coefficients more efficiently, leveraging techniques from NTRU Prime. This optimization addresses practical constraints in network protocols like IPv6 MTU limits. The approach is experimental and comes with a disclaimer about potential cryptographic risks.
Background
ML-KEM-768 is a post-quantum cryptographic algorithm selected by NIST for standardization, with public keys traditionally encoded at 1184 octets. IPv6 networks have a maximum transmission unit (MTU) of 1280 bytes, creating payload size constraints for protocols using UDP.
