Abstract
A hybrid cryptographic encoding system is disclosed in which plaintext is encrypted using AES256-GCM keyed via an X25519 ephemeral-static Diffie-Hellman key agreement, optionally protected at rest by a Shamir K-of-N secret-sharing scheme whose shares are individually gated by biometric fuzzy extractors, and the resulting authenticated ciphertext is rendered through a pluggable steganographic output layer (key-permuted Morse, Base64, or linguistic steganography). The combination delivers confidentiality, integrity, forward secrecy, threshold multi-party access control, and format-agnostic camouflage in a single interoperable pipeline.
