Abstract
Intrusion Detection Systems have to match large sets of regular expressions to detect malicious traffic on multi-gigabit networks. Many algorithms and architectures have been proposed to accelerate pattern matching, but formal methods for reduction of Nondeterministic finite automata have not been used yet. We propose to use reduction of automata by similarity to match larger set of regular expressions in FPGA. Proposed reduction is able to decrease the number of states by more than 32% and the amount of transitions by more than 31%. The amount of look-up tables is reduced by more than 15% and the amount of flip-flops by more than 34%.
