| Research Abstract |
We have newly proposed a regular expression matching hardware engine based on a systolic algorithm, in which virus patterns can be set during the execution, for network intrusion detection. We have also presented a matching engine for approximate regular expression matching, in which regular expression matching and approximate string matching were combined. From those results, it has become possible to construct a network intrusion detection system, which can handle unknown network viruses in a flexible and efficient manner.
