Abstract

A CRC rule is generated for each CRC parity check circuit from a bank of CRC parity check circuits for mapping a fixed-length CRC output to a signature, each of the CRC parity check circuits servicing a specific string length. The selected CRC parity circuit outputs a fixed-length parity-check data for the specific data packet, and the string mapper maps the fixed-length parity-check data for the specific data packet to one of the string identifiers associated with the group of signatures. If a fixed-length parity-check match is found, outputting a string identifier of the match for a security action.
