ABSTRACT:
A keystream generation system for producing a cryptographically secure keystream by an "amorphous" process. Three types of keystream generation are preferred. A large seed key is directly amorphously expanded into a cryptographically secure keystream. A small seed key seeds a pseudo random number generator whose output is made cryptographically secure through a contracting amorphous process or, alternately, the security of an extended keystream is strengthened through contraction. Finally, a state machine whose output and transition functions are based on amorphousness recursively operates on a seed key to generate an arbitrarily long, cryptographically secure, keystream. The recursive performance of such amorphous logical operations on seed keys in order to generate keystreams is akin to the encryption of data.
