(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
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...
In this work, we construct a fuzzy identity based signature (FIBS) scheme based on the Small Integer Solution (SIS) Problem. FIBS schemes allow a user with identity id to issue a signature which could be verified under identity id′ if and only if id and id′ are close to each other....
The short integer solution problem SISn,q,β,m is as follows. Given a uniform random matrix A ←−$ Znq ×m, find a non-zero vector e ∈ Zm such that Ae = 0 (mod q) and e ≤β. We define the advantage (function of the security parameter λ) of an algorithm A in solving ...

Another set of superlattice reflections with (2H,2K,2L) all odd comprise the set of half-integer (H,K,L) values such as (1/2,1/2,1/2) and also have an intensity of N2z2|fA− fB|2. We can also apply the microdomain model to the pure D03 SRO in the same fashion as in ...

When some variables are forced to be integer (ILPs), you can solve a lot of useful problems like scheduling, routing, and packing. That’s basically how all supply chain optimization works. I'll be at the JMM2025-01-07#shortform I’ll be at the Joint Mathematics Meeting in Seattle (...
