Deep packet inspection (DPI) has become one of the key components of a Network Intrusion Detection System (NIDS) and it compares packet content to a set of rules written in regular expression. The need to keep up with ever-increasing line speed has forced NIDS designers to move to hardware or high-speed memory where memory resources are limited. In this paper, we present LBM, a novel accelerating scheme for regular expression matching which converts the original byte stream into much shorter… CONTINUE READING
