Latest Patents

Timothy Hahn holds a patent titled "Use of packet hashes to prevent TCP retransmit overwrite attacks." This invention focuses on systems that detect maliciously formed TCP/IP retransmit packets attempting to pass through an intrusion detection system (IDS). The system is designed to prevent these packets from reaching their destination by enforcing early flow termination. The IDS tracks a hash of specific fields in each packet, maintaining a set of hashes for all packets in the currently open TCP window for each flow. If the hash of a retransmit packet does not match the cached hash of the corresponding original packet, the system concludes that an attack is underway and terminates the flow. The hash function can vary in complexity and security, ranging from low complexity to high complexity and high security.
