Publication number: 20140074719Abstract: An accelerated transparent authenticated Data Exchange system wherein the chronology of alternating senders' and receivers' messages are authenticated typically at each step, with an easy to use provision for resending, in the event of faulty transmission, such that the final message hash value authenticates the negotiation chronologically from first to final message, wherein the final hash value is operative to enable a signature of an entity or entities which binds such entity to the whole data exchange, which signature can be in clear text, encoded, and/or encrypted with authentication integrity. The system is useful for managing computerized negotiations including client-initiated computerized negotiations and including computerized financial transactions.Type: ApplicationFiled: July 18, 2013Publication date: March 13, 2014Inventors: Carmi David Gressel, Richard Daniel Pinnick, Nicolas Tadeus Courtois, Gabriel Vago, Gregory Van Bard, Ran Granot, Avi Hecht

Patent number: 7852162Abstract: Random number generators are used for entertainment in gambling, lotteries and video gaming devices. True Random Number Generators, as are now currently defined, must be actuated by a physical noise source, typically based on the uncertainty of the phase differences of a stable and an unstable autonomous oscillator. In this invention an autonomous random frequency modulated oscillator driven by a self contained pseudo-random number generator outputs three loosely correlated random binary streams. Included in the invention is a hardware method for proving wandering phase differences and also the existence of a colored random distribution of concatenated nibbles.Type: GrantFiled: May 25, 2006Date of Patent: December 14, 2010Assignee: FortressGBInventors: Carmi David Gressel, Avi Hecht, Ran Granot

Patent number: 7827223Abstract: Systems and methods are disclosed, especially designed for very compact hardware implementations, to generate random number strings with a high level of entropy at maximum speed. For immediate deployment of software implementations, certain permutations have been introduced to maintain the same level of unpredictability which is more amenable to hi-level software programming, with a small time loss on hardware execution; typically when hardware devices communicate with software implementations. Particular attention has been paid to maintain maximum correlation immunity, and to maximize non-linearity of the output sequence. Good stream ciphers are based on random generators which have a large number of secured internal binary variables, which lead to the page synchronized stream ciphering. The method for parsed page synchronization which is presented is especially valuable for Internet applications, where occasionally frame sequences are often mixed.Type: GrantFiled: April 21, 2005Date of Patent: November 2, 2010Assignee: Fortress GB Ltd.Inventors: Carmi David Gressel, Michael Slobodkin, Ran Granot, Roy Krotman, Yehonatan Bick, Mark Fiterman, Gabriel Vago, Amir Ingher, Uzi Apple

Publication number: 20070283145Abstract: A system for multi-factor security involving multiple secure devices that distribute the secured functions of the system over the different devices, such that the loss or theft of any one of them does not compromise the overall security of the system. Moreover, a configuration of devices is also secure even if one of them has been attacked by malicious software agents, such as “keyboard sniffers”. A novel contactless smart card reader (200) is presented that incorporates a transceiver antenna (220) within a keypad (210) of a device used with contactless smart cards (100). When the card (100) is pressed against the device's keypad (210), the transceiver (220) of the device establishes a session with the smart card (100). A variety of systems are presented, including those using mobile telephones, computer-interfaced card readers, personal digital appliances, and television set-top box remote controllers.Type: ApplicationFiled: July 24, 2007Publication date: December 6, 2007Inventors: Carmi Gressel, Gabriel Vago, Ran Granot, Torner Kanza, Uzi Apple, Avi Hecht
