Architectures for Bit-Split String Scanning in Intrusion Detection
Lin Tan, Timothy Sherwood · IEEE Micro · 2006
String matching is a critical element of modern intrusion detection systems because it lets a system make decisions based not just on headers, but actual content flowing through the network. Through careful codesign and optimization of an architecture with a new string matching algorithm, the authors show it is possible to build a system that is almost 12 times more efficient than the currently best known approaches.
