ABSTRACT:
A microprocessor configuration includes a data bus for data transfer between functional units. On the bus side, each unit contains an encryption/decryption unit that is controlled synchronously by a random number generator. The configuration permits a relatively high level of security against monitoring of the data transferred via the data bus, with a feasible level of additional circuit complexity.
