MULTISTREAM ENCRYPTION SYSTEM FOR SECURE COMMUNICATION

摘要

MUSE, a programmable multistream encryption system for secure communication provides dynamic cryptographic security and a highly efficient surveillance mechanism for transferring very large blocks of data (VLBD) subject to real-time constraints. Encryption varies pseudorandomly in both space and time. MUSE allows the user to specify a finite state machine (21) which sequentially accepts parallel streams of data (VLBD) and encrypts this data in real time employing an arithmetic-algebraic pseudorandom array generator (41) (PRAG). The method of enciphering is a one-time algebraic pad system which views the incoming data streams as elements from an algebraic alphabet (finite ring) and encrypts by adding to this a pseudorandom vector sequence (21) iteratively generated from a single seed key (20). Decipherment is obtained by reversing this process.
