本申请公开了一种基于AVX512IFMA的椭圆曲线的并行点加方法,属于计算机技术领域。方法包括:确定参与并行点加的多对点数据的坐标中的每个坐标;确定多对点数据对应的目标数域,目标数域为椭圆曲线的有限域或者有限域的二次扩域;确定对应于目标数域的大数运算规则;基于多对点数据中每对点数据中加点数据的Z坐标值Z 法律状...
This paper studies methods for using Intel's forthcoming AVX512IFMA instructions in order to speed up modular (Montgomery) squaring, which dominates the cost of the exponentiation. We further show how a minor tweak in the architectural definition of AVX512IFMA has the potential to further speed ...
(GMP). The essential computation of the scheme relies on the modular exponentiation, and our library takes advantage of two Intel features - the multi-buffer modular exponentiation function (mbx_exp_mb8) of IPP-Crypto library, which is enabled in AVX512IFMA instruction sets supporting SKUs, ...
IFMA全称当然是integer fused multiply-add,但实际其还有一个后缀,那便是52,也就是AVX512 IFMA52,包含两个指令,即VPMADD52LUQ和VPMADD52HUQ,分别为取低(L)52位和高(H)52位无符号整数(U)尾数结果,产生104位的整数结果,这还并不是想象中的128位,这与其本质为64位浮点FMA单元共用设计的原因有关,双精度64位...

Montgomery multiplicationIntel AVX-512IFMA instructionsIn this paper, we propose a fast implementation of multiple Montgomery multiplications using Intel AVX-512IFMA (Integer Fused Multiply-Add) instructions. The proposed implementation is based on a modified Montgomery multiplication. For Montgomery ...
