  • Patent number: 7140041
    Abstract: A method, system and computer program product for detecting the dissemination of malicious programs. The degree of randomness in the Internet Protocol (IP) destination addresses of received IP packets to be forwarded to an external network may be detected by performing a hash function on the IP destination addresses thereby generating one or more different hash values. If a high number of different hash values were generated for a small number of IP packets examined, then random IP destination addresses may be detected. By detecting random destination IP addresses, the dissemination of a malicious program, e.g., virus, worm program, may be detected.

  • Patent number: 7106860
    Abstract: A system and method is presented for enciphering information using the Advanced Encryption Standard (AES) algorithm in which a subprocessor is configured to manipulate data as it is being loaded into the subprocessor memory. Thus, unlike implementations in the prior art, which require complete loading of data into a subsystem memory before data manipulation thereby creating a potential bottleneck in memory, this invention reduces the potential bottleneck in memory.
