提出了一种应用于椭圆曲线密码体制中的有限域乘法器结构,基于已有的digit-serial结构乘法器,利用局部并行的bit-parallel结构,有效地省去了模约简电路,使得乘法器适用于任意不可约多项式;通过使用数据接口控制输入数据的格式并内嵌大尺寸乘法器,可以配置有限域乘法器的结构,用以实现基于多项式基的有限域乘法运算。该结构可以有效满足椭圆曲线密码体制的不同安全需求。
A finite-domain multiplier structure for elliptic curve cryptosystem is proposed. Based on the existing digit-serial structure multiplier, the local parallel bit-parallel structure is used to effectively eliminate the modulo circuit and make the multiplication It is suitable for any irreducible polynomial. By using the data interface to control the format of input data and embedding large-scale multipliers, the structure of the finite field multiplier can be configured to implement finite field multiplication based on polynomial basis. The structure can effectively satisfy the different security requirements of elliptic curve cryptosystem.
