Abstract
A process for comparing data, such as signatures in a data packet, includes retrieving, from a first hash table, a target value that corresponds to a segment of the data, processing the data in accordance with the target value to produce a checksum, locating an entry in a second hash table using the checksum, and comparing the data to the entry.
