Abstract: Apparatus, system and method for authenticating a device for secure network communication. Identification data is configured as a hash of a public key for identifying at least one of the device and/or a user associated with the device. An Internet Protocol (IP) message may be generated, wherein an IP source address in the IP message includes the identification data. The device may register with a server by transmitting the IP message and the public key and subsequently generate and transmit a second IP message, wherein an IP source address of the second IP message includes the identification data. The server may issue a challenge to the device in response to the second IP message, wherein the challenge is based at least in part on the identification data. After receiving the challenge, the device may transmit response data to the server for authenticating the device for secure network communication.

Abstract: At a transmitter node, a commitment value C is obtained as a function of a message m. The commitment value C and transmitter terms of use TA for the message m are then sent to a receiver node without disclosing the message m. A cryptographic receiver signature SB over the commitment value C and the transmitter terms of use TA is received from the receiver node, where the cryptographic receiver signature SB is signed with a private key kprv-B associated with the receiver node. The receiver signature SB may be authenticated using a public key kpuh-B for the receiver node. If the receiver signature SB is successfully authenticated, the message m and the receiver signature SB are signed using a private key kprv-A for the transmitter node to obtain a transmitter signature SA. The message m and the transmitter signature SA may then be sent to the receiver node.
