(Short Integer Solution(SISq,n,m,β)):给定m个均匀随机的向量ai∈Zqn,它们构成矩阵A∈Zqn×m的列,要求找到一个非零整数向量z∈Zm,满足范数‖x‖≤β,并且使得 (1)fA(x):=Ax=0∈Zqn以下是几点对于SIS问题的说明: 在没有对‖x‖的约束时,可以通过高斯消元法轻松找到一个解。类似地,必须取β...
Short integer solution(SIS)Key exposure is a severe threat in digital signature, the scheme will be compromised provided that the private key of the signature is revealed. To remove the destruction of key exposure, the private key must be kept updated in the process of the signature. As a ...
Short integer solution problem (SIS)SWIFFT hash functionSubset-sumKnapsacksThe paper is about algorithms for the inhomogeneous short integer solution problem: Given (A, s) to find a short vector x such that Ax 鈮 s (mod q). We consider algorithms for this problem due to Camion and Patar...
