ABE for DFA from k-Lin
ABE DFA
2019/6/4
We present the first attribute-based encryption (ABE) scheme for deterministic finite automaton (DFA) based on static assumptions in bilinear groups; this resolves an open problem posed by Waters (CRY...
Recently, the NIST launched a competition for lightweight cryptography and a large number of ciphers are expected to be studied and analyzed under this competition. Apart from the classical security, ...

We present an adaptively secure functional encryption (FE) scheme based on deterministic finite automata (DFA). The construction uses composite-order bilinear pairings and is built upon the selectivel...
基于状态分组的高效i-DFA构造技术
正则表达式 状态膨胀 状态分组 局部搜索
2014/3/21
正则表达式匹配在很多网络安全领域起着非常重要的作用。确定性有限自动机 (DFA, deterministic finite automaton) 具有线速稳定的匹配性能，因而更适合在高速网络环境下执行正则表达式匹配。但DFA可能由于状态膨胀而占用巨大的内存空间。作为状态膨胀问题的一种经典解决方案，i-DFA在大幅降低内存开销的同时，还能保证最差匹配性能。然而，已有方法构造i-DFA时在时间和空间上...
基于确定性有限自动机(DFA)的传统正则表达式匹配方法存在单周期处理单字符的速度瓶颈。为提升处理速率，提出一种单周期处理多字符的匹配算法MC-DFA，该算法基于DFA实现，支持匹配位置的精确定位。MC-DFA将传统DFA中的单字符跳转合并为多字符跳转，实现了单周期处理多个输入字符。通过状态转移矩阵二阶压缩算法，MC-DFA分别对矩阵行内以及行间冗余进行消除，减少了内存使用。300条规则下，单周期处...
