A fuzzy comprehensive assessment method of running condition was constructed and applied to a large-scale centrifugal compressor set in a petrochemical corporation aiming at the monitoring and early w...
Lattice-Based Remote User Authentication from Reusable Fuzzy Signature
Lattice-Based Cryptography Fuzzy Signatures Biometrics Reusability
2019/6/26
In this paper, we introduce a new construction of lattice-based reusable fuzzy signature for remote user authentication that is secure against quantum computers. We define formal security models for t...
Obfuscated Fuzzy Hamming Distance and Conjunctions from Subset Product Problems
Program Obfuscation Hamming Distance Conjunctions
2019/6/4
We consider the problem of obfuscating programs for fuzzy matching (in other words, testing whether the Hamming distance between an nn-bit input and a fixed nn-bit target vector is smaller than some p...
We introduce and study the notion of keyless fuzzy search (KlFS) which allows to mask a publicly available database in such a way that any third party can retrieve content if and only if it possesses ...
给出了一种R-fuzzy集隶属度的权重比较与量化方法, 提出了优势测度概念, 解决了粗糙近似集中隶属度的重要性难以确定的问题. 首先给出优势测度的定义, 然后, 研究了优势测度的性质, 指出了优势测度1型模糊集的本质属性. 优势测度不仅实现了R-fuzzy集隶属度的量化, 而且成为R-fuzzy集与2型模糊集联系的纽带. 通过隶属度的优势测度, 实现了人类感知领域中的群体共识与个性认识的区分, 反...
Robustly reusable Fuzzy Extractor (rrFE) considers reusability and robustness simultaneously. We present two approaches to the generic construction of rrFE. Both of approaches make use of a secure ske...
基于AHP-FUZZY的地震危险度评价初探
AHP-FUZZY 天津 地震危险度评价
2019/1/4
以天津地区为例，通过对断裂构造及地震等基础资料的分析处理，建立了适合大区域的地震危险水平评价方法体系，利用层次分析法确定该评价指标体系中评价因子的权值，运用两级模糊综合评判法对研究区的危险水平分区进行定量评价，最终根据最大隶属度原则得出天津地区危险度评价结果。结果显示：极高危险区基本分布在塘沽、津南区葛沽镇、宁河区及蓟运河断裂附近；高危险区主要分布在天津市区部分区域、蓟州区桑梓镇及极高危险区周边等...
