Title: Method for utilizing an encrypted key as a key identifier in a data packet in a computer network
Inventor: KAUFMAN CHARLES W
IPC: G09C1/00
Filed: 1990-06-05
Abstract: Abstract of the Disclosure The nodes in a computer network utilize an encrypted key as a key identifier in a data packets transferred between nodes which eliminates the need for a receiving node to perform a memory look up operation to ascertain the key used to encrypt the data.  Each node is provided with a master key that is unique to each node.  When two nodes want to establish communications they first negotiate a shared key.  This shared key is then encrypted under each nodes' master key.  The nodes then exchange their respective encrypted key.  The encrypted key of the receiving node is placed in the data packet to be sent by the transmitting node.  Upon receiving a data packet, the receiving node decrypts the encrypted key to determine the shared key.  This shared key is then used to decrypt encrypted data in the data packet.

Title: Photo-receiver
Inventor: SHIGA NOBUO
IPC: H04B10/80
Filed: 1990-10-11
Abstract: ABSTRACT OF THE DISCLOSURE   A case where a high bias voltage is required for a photo-element of a photo-receiver, a high voltage is applied to an amplifier which amplifies a photo-current created by the photo-element, when a power supply is turned on.  In a prior art photo-receiver, the amplifier may be broken due to this high voltage.  In the present invention, the photo-receiver is provided with a protection circuit comprising a diode connected between a power supply circuit and a photo-element, a resistor connected in parallel with the diode, and a first capacitor having one end thereof connected to an anode of the diode and the other end thereof connected to a reference potential.  Constants of the circuit components are set such that a time constant of the supply of the power to the amplifier is smaller than a rising time constant of the supply of the power to the photo-element and larger than a falling time constant of the supply of the power to the photo-element.          Accordingly, the supply of the power to the photo-element is started after the potential at the input terminal of the amplifier has been established and the potential at the input terminal of the  amplifier floats after the supply of the power to the photo-element has been fully extinguished.  As a result, the amplifier is not broken at the time of power-on and a surge voltage is not applied to the input terminal of the amplifier at the time of power-off.
