  • Patent number: 7224594
    Abstract: A glitch protect valid cell and method for maintaining a desired logic state value. The glitch protect valid cell includes a memory element, a state machine, and a glitch protect circuit. The glitch protect circuit includes a propagation delay assembly coupled to a restore assembly. The propagation delay assembly includes a first pull down network coupled to a NOR gate. The restore assembly includes a second pull down network coupled to the propagation delay assembly. Responsive to a glitch signal and timing signal, the first pull down network resets the initial state value of a true valid bit to ultimately enable a pull up network in the NOR gate. Responsive to enablement of the NOR gate pull up network, the second pull down network resets the complement valid bit in the memory element to consequently restore the initial state of the true valid bit.

  • Patent number: 7142672
    Abstract: A method (300) and system for transmitting sensitive information from a client computer to a service provider operating in the INTERNET. The sensitive information (for example a credit card number for carrying out an e-commerce transaction) is split (318) into several chunks, which are meaningless when taken alone. Each chuck is inserted (339) into a corresponding data frame, adding noise information. Information about how to extract each chunk from the corresponding data frame and how to use the chunks to reconstruct the original sensitive information is inserted (336) into a control frame. The data and control frames are distributed (354, 363) to different interface computers of the INTERNET; the frames are then forwarded (366) to the server computer, which is not connected to the INTERNET directly but communicates through a secure private network with the interface computers.
