Abstract
The first and second devices exchange randomly generated messages that are used in a composition-based encryption/decryption process. At least one of the randomly generated messages is, itself, encrypted before transmission. The composition-based process (a cyclic redundancy code process, preferably enhanced with midcycle non-Galois Field operation) is embedded in both devices and not readily discernable by playback attack.
