Abstract

A low-cost cryptographic processor for security embedded system is presented in this paper. The processor, without any assistance of dedicated cryptographic coprocessors, is scalable and very efficient for popular cryptographic algorithms such as RSA/ECC, AES, Hash, etc. Based on SMIC 0.18um standard CMOS technology, the core circuit of the test chip has only about 32k gates, and a max frequency of 200MHz, under which the 1024-bit RSA algorithm takes only 150ms and the throughout of AES reaches 256Mbits/s.
