Abstract

A multi-task-oriented security processing architecture is presented in this paper. This architecture contains a host microprocessor and multiple security processors (SP). The SP could integrate dedicated Crypto-Engines, which provides functional extensibility. And the performance scalability and multi-task parallelism could be enhanced by increasing the number of SPs on system bus. It's demonstrated that this architecture greatly improves the system efficiency. A test chip is implemented based on SMIC 0.18 um standard CMOS technology, and its functionality is well verified.
