Fast Regular Expression Matching Using FPGA
Original language description
With the growing number of viruses and network attacks, Intrusion Detection Systems have to match a large set of regular expressions at multi-gigabit speed to detect malicious activities on the network. Many algorithms and architectures have been designed to accelerate pattern matching, but most of them can be used only for strings or a small set of regular expressions. The capacity of available FPGA chips is a limitation for architectures based on a nondeterministic finite automaton. Therefore we propose new algorithm to find a non-collision set of states which enables to map a part of the transition table to the memory instead of the FPGA logic cells. For all analysed sets of regular expressions, the algorithm was able to find a non-collision set with 61.4% of states in average and a non-collision set with 83.6 % of states for the best case. System of Parallel Automaton Parts is introduced, it is a model which represent a division of the automaton by sets of states. New NFA Split ar
