  • Computer network encryption/decryption device
    Patent number: 5640456
    Abstract: A computer network encryption/decryption device includes at least one microprocessor, microprocessor support hardware, at least two network ports for connecting to upstream and downstream networks, memory hardware for storing program, configuration, and keylist data, and data encryption/decryption hardware. Both network ports have the same network address, making the device transparent to the local area network in which it is spliced. The device operates by selectively encrypting or decrypting only the data portion of a data packet, leaving the routing information contained in the header and trailer portions of the data packet unchanged.
    Type: Grant
    Filed: July 10, 1995
    Date of Patent: June 17, 1997
    Assignee: Uunet Technologies, Inc.
    Inventors: Richard L. Adams, Jr., Peter D. Hallenbeck
  • Computer network encryption/decryption device
    Patent number: 5444782
    Abstract: A computer network encryption/decryption device includes at least one microprocessor, microprocessor support hardware, at least two network ports for connecting to upstream and downstream networks, memory hardware for storing program, configuration, and keylist data, and data encryption/decryption hardware. The device operates in one of two modes by selectively encrypting or decrypting packets or portions of packets based on information contained in a packer's header.
