This work deals with off-boding some time critical parts in the process of performing intrusion detection from software to reconfigurable hardware (FPGA). Signatures of known attacks must typically be compared to high speed network traffic, and string matching becomes a bottleneck Content Addressable Memories (CAMS) are known to be fast string matchers, but offer little flexibility. For that purpose a Variable Word- Width CAM for fast string matching has been designed and implemented in an FPGA… CONTINUE READING
