Abstract:
A packet verification system for verifying message packets intercepted over a network, the packet verification system comprising:A. a processed packet store configured to store a header and a series of processed message packets each processed message packet including a message packet and a hash value; and B. a packet verification processor configured to, in verification of a selected one of said processed message packets in said series, process successive processed message packets prior thereto in the series, for each processed message packet, as a current processed message packet, the packet verification processor being configured to process the message packet of the current processed message packet and a hash value associated with a hash value associated with a previous processed message packet in the series in connection with a selected hash algorithm thereby to generate a hash value for the message packet, compare the generated hash value to the hash value associated with the current processed message packet and determine whether the message packet is verified based on the comparison.
