Design of an efficient elliptic curve cryptography coprocessor

Elliptic curve cryptography plays a crucial role in networking and communication security. FPGA based architecture of elliptic curve cryptography coprocessor is proposed in this paper. The coprocessor contains the operation over binary finite fields, point adding, doubling and scalar multiplication on elliptic curve. In this coprocessor a new type of FPGA-based modular multiplier architecture is proposed. Experiment results show that coprocessor designed can achieve high performance. The coprocessor embedded in PCI adaptor is realized for encryption and decryption.
