Pattern matching is the most computation intensive task of a network intrusion detection system (NIDS). In this paper we present a hardware architecture to speed up the pattern mat...
Deep Payload Inspection systems like SNORT and BRO utilize regular expression for their rules due to their high expressibility and compactness. The SNORT IDS system uses the PCRE ...
In this paper, we propose a regular expression matching circuit based on a decomposed automaton. To implement a regular expression matching circuit, first, we convert regular expr...
—We present algorithms for implementing large-scale regular expression matching (REM) on FPGA. Based on the proposed algorithms, we develop tools that first transform regular ex...
An approach is presented for high throughput matching of regular expressions (regexes) by first converting them into corresponding Non-deterministic Finite Automata (NFAs) which a...
