Abstract
Based on modified multiple-word radix-4 Montgomery algorithm and improved pipeline mechanism, an area efficient RSA crypto-processor is implemented, which supports reconfigurable keys up to 2048 bits. Based on 0.25mum standard CMOS technology, the new coprocessor achieves a 1024-bit encryption rate of 28Kbps at 180MHz and the core circuit without RAM contains 18,000 gates. The result shows that this processor is very suitable for area-constrained applications such as smart cards
