HashMem is a memory based, exact pattern matching architecture for Snort-like intrusion detection. It uses CRC- style functions to determine a unique location for a possible match and then matches the input against the pattern stored in the specified memory location. This approach achieves is a very low logic and a reasonable memory cost. In this paper we extend the HashMem architecture to allow storing of variable-length patterns in a single memory structure, reducing the number of required… CONTINUE READING
