Abstract: | Microprocessors are playing an increasingly important role in cryptographic systems. ROTERM is an implementation of a cipher terminal using an inexpensive microcomputer system. ROTERM behaves like a mechanical rotor system of eight rotors with 96 elements each. Control features have been implemented in ROTERM which permit keyboard and/or remote control of the encipherment and decipherment of ASCII character strings. Examples are given demonstrating the use of ROTERM in user-user communications as well as user-electronic mail system posting and reading of messages. |
