Abstract

The research into developing faster microproces- sors may pose a threat to encrypted communica- tions. As faster microprocessors are developed, means of "breaking" encryption Key Variables (i.e. by exhaustive search methods) will be accomplished with relative speed, thus providing less secure means of communication. Providing a means ofvarying the encryption Key Variables throughout a call elimi- nates this possibility of "breaking" all the Key Vari- ables in a useful time lapse.
