Title: Stateless, Ephemeral Identity-Based Encryption via Chaotic Mutual Derivation
Authors: COŞAR, CAN BERK

Subject Terms: Computer Science, Cryptography and Security, Stateless encryption, Chaotic cryptography, Identity-based encryption, Ephemeral key derivation, Forward secrecy, Information Theory
Description: This study introduces a novel cryptographic framework that facilitates end-to-end encryption without the reliance on pre-established secrets, long-term key storage, or third-party trust anchors. Security is achieved solely through the mutual possession of ephemeral identifiers and per-message entropy. Each message is independently encrypted using a deterministic yet chaotic key derivation process, seeded by the concatenation of two device identities and a transient random value. The proposed method is entirely stateless, ephemeral, and symmetric in decryption capability. It provides strong resistance to session-based attacks, enforces forward secrecy by design, and lays the groundwork for private, decentralized, and transient communication protocols. This approach provides a viable alternative to traditional key exchange systems through its identity-driven architecture, and introduces an encryption model particularly suitable for mobile and embedded applications due to its minimal resource requirements.
