英文摘要：

This paper proposes a unified hardware architecture which can accelerate both RSA and SHA-1 calculations. And a scalable and unified crypto function unit is presented to support high performance cryptographic computation in the RISC-like processor. To evaluate the effectiveness of our solution, a crypto-processor is employed to integrate the proposed function unit, and the execution time of 1 024 bit RSA is 190 ms and SHA-1 encryption rate reaches 64 Mbps. According to the synthesis results based on SMIC 0.18 micron library, the unified crypto function unit can achieve 196 MHz work frequency with the utilization of 2.6 thousand gates.
