Abstract
A system for providing high security for data stored in memories in computer systems is disclosed. A different encryption key is used for every memory location, and a write counter hides rewriting of the same data to a given location. As a result, the data for every read or write transaction between the microprocessor and the memory is encrypted differently for each transaction for each address, thereby providing a high level of security for the data stored.
