Abstract

Provided is a pattern matching engine. The pattern matching engine calculates an error detection sign of target data and compares the calculated error detection sign with an error detection sign of a malware pattern DB. When the error detection sign of the target data and the error detection sign of the malware pattern DB are identical to each other, the pattern matching engine compares the target data with the malware pattern.

First claim

What is claimed is:

1. A pattern matching engine, comprising:
an error detection sign comparison unit which calculates an error detection sign of sub-data, which is a part of target data, and compares the calculated error detection sign with an error detection sign of a malware pattern;
a matcher which, when the error detection sign of the sub-data and the error detection sign of the malware pattern are identical to each other, compares the sub-data with the malware pattern;
a…
