MULTI-HOP SECURE CONTENT ROUTING BASED ON CRYPTOGRAPHIC PARTIAL BLIND SIGNATURES AND EMBEDDED TERMS

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.
