A new self-synchronizing stream cipher (SSSC) is proposed based on one-way and nearest neighbor coupled integer maps. Some ideas of spatiotemporal chaos synchronization and chaotic cryptography are applied in this new SSSC system. Several principles of constructing optimal SSSC are discussed, and the methods realizing these principles are specified. This SSSC is compared with several SSSC systems in security by applying chosen-ciphertext attacks. It is shown that our new system can provide SSSC with high security and fairly fast performance.
