  • Access system
    Patent number: 7118033
    Abstract: An access system includes an input device which is accessible to a user and capable of reading an authentication and/or identification information provided by the user. The access system further includes a Wiegand control panel (12) connected to the input device for evaluation of the information provided by the user. The control panel (12) is located in a secure area (14) remote from the input device. The access system further includes a converter (18) connected to the input device and to the control panel (12). The input device includes encryption means to encrypt the information provided by the user. The converter (18) is capable of converting the encrypted information into a standard Wiegand signal.

  • Signal filtering mechanism for a multi-purpose digital television receiver
    Patent number: 6628891
    Abstract: Conditional access methods and apparatus are provided for use with digital television receivers and other digital broadband receivers. The methods and apparatus are capable of handling several different digital signal transmission protocols in an automatic and flexible manner. An input unit is provided for analyzing and tagging incoming data bytes so that further processing operations are less dependent on the transmission format being received. A cipher handling unit is provided for adapting in real time the scrambling and descrambling performances to match the requirements of the transmission network and the receiving apparatus. A filtering mechanism is provided for filtering and handling multiple asynchronous data streams in a parallel manner. A private recording mechanism is provided for making a private copy of selected incoming signals.

  • Pad encryption method and software
    Patent number: 6324287
    Abstract: A pad encryption software architecture includes space on a floppy for storing the pad to be used with the encryption software. The pad is XOR generated with random numbers subject to redetermined offsets. If the pad is smaller than the text to be encrypted, then XOR takes several cycles with redetermined offsets used in XORing the pad with the remaining plain text to be encrypted. The offset is determined from a user selected password. New offsets are determined from old offsets by adding the current offset to the value of the byte in the pad located at the offset value.
