  • Publication number: 20120011584
    Abstract: A system and method that provides for copying ARP replies, and generating data packets which include the ARP reply, and other information such as an identification of the port on the ARP reply was received. These data packets are then transmitted to an ARP collector which stores the ARP reply and port information. The ARP collector then uses this stored information, and analyzes future data packets relative to the stored information to detect occurrences of ARP spoofing. The ARP collector further provides for generating alerts and taking security actions when ARP reply spoofing is detected.

  • Patent number: 8094771
    Abstract: The invention describes a product and a method for generating electrical power directly from nuclear power. More particularly, the invention describes the use of a liquid semiconductor as a means for efficiently converting nuclear energy, either nuclear fission and/or radiation energy, directly into electrical energy. Direct conversion of nuclear energy to electrical energy is achieved by placing nuclear material in close proximity to a liquid semiconductor. Nuclear energy emitted from the nuclear material, in the form of fission fragments or radiation, enters the liquid semiconductor and creates electron-hole pairs. By using an appropriate electrical circuit an electrical load is applied and electrical energy generated as a result of the creation of the electron-hole pairs.
