Abstract

Digital voice and data encryption requirements con- tinue to grow in the industry The application of time division multiplexing techniques to high speed encryption key generator devices or algorithms can increase the flexibility and ease of management of cryptographic sys- tems with multiple key variables. This technique, coupled with newly emerging low bit-rate voice coding techniques and high speed processing capability, makes this technique especially useful for encrypted voice communication applications as well.
