Latest Patents

One of Tzadikario's latest patents is titled "Using TCP to authenticate IP source addresses." This method involves intercepting requests directed over a network to authenticate communication traffic. It includes a handshake procedure specified by a predetermined communication protocol. A reply to any request that deviates from this procedure is sent to the source address. The response from the source address is then analyzed to assess its legitimacy. If deemed legitimate, the target computer is allowed to complete the handshake procedure to establish a connection.

Another significant patent is "Using threshold lists for worm detection." This computer-implemented method screens communication traffic by defining a list of threshold pairs with respective first and second threshold values. The method monitors network traffic from various sources to determine the count of unique destination addresses each source has transmitted data to during a specific time period. A response to malicious network traffic is triggered when certain conditions are met, ensuring enhanced security against potential threats.
