Abstract: This paper presents a high-speed Elliptic Curve Cryptography(ECC) co-processor suitable for both prime number field and binary field, which supports all curve and field polynomials. The co-processor can implement all basic operations used in ECC and perform ECDSA and other modified algorithms by instructions. Operands of the co-processor can be of any length no more then 384 bit. Many methods such as word-level multiplier, separate operands and RAM array are used to improve the performance of the system.

Key words: Elliptic Curve Cryptography(ECC), dual field, word-level multiplier, RAM array, digital signature

摘要： 提出一种能同时在素数域和二进制有限域下支持任意曲线、任意域多项式的高速椭圆曲线密码体系(ECC)协处理器。该协处理器可以完成ECC中的各种基本运算，根据指令调用基本运算单元完成ECDSA及其他改进算法。支持384位以下任意长度的ECC应用，采用基于字的模乘器、操作数分离、RAM阵列等技术提高系统性能。
