Richard John Keefe has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Encryption/decryption device for secure communications between a protected network and an unprotected network and associated methods
    Patent number: 9083683
    Abstract: The encryption/decryption device includes a plaintext unit, a ciphertext unit and a cryptographic unit connected therebetween. The plaintext unit may include a logic device such as a first programmable logic device (PLD), e.g. a field programmable gate array (FPGA), for interfacing with the protected network to perform encapsulation of data from the protected network to define outgoing datagrams, and to perform decapsulation of incoming datagrams from the cytographic unit. The ciphertext unit may include a second logic device such as a PLD or FPGA for interfacing with the unprotected network to perform routing of incoming encrypted datagrams from the unprotected network to the cryptographic unit, and to perform routing of outgoing encrypted datagrams from the cryptographic unit to the unprotected network.
