Abstract :
A new RSA/ECC coprocessor with the characteristic of reconfiguration is proposed in this paper, which can meet the requirements of both GF(p) and GF(2\´") fields and perform the prevalent cryptographies such as RSA and ECC. The coprocessor has the merit of reconfigurable architecture, and it can perform the modular multiplication from 32-bit to 512-bit without any modification to its hardware. Based on 0.35 μm CMOS technology, area of the coprocessor is about 45K gates, and system frequency can up to 100MHz, the 512-bit modular multiplication achieve 190kbps and the 233-bit ECC encryption rate of 50kbps.
