Kemeleon encodings

Abstract

This document specifies Kemeleon encoding algorithms for encoding ML-KEM public keys and ciphertexts as random bytestrings. Kemeleon encodings provide obfuscation of public keys and ciphertexts, relying on module LWE assumptions. This document specifies a number of variants of these encodings, with differing failure rates, output sizes, and performance profiles.

Keywords: post-quantum cryptography, obfuscation
