Abstract
Methods and systems for providing confidentiality of communications sent via a network that is efficient, easy to implement, and does not require significant key management. The identity of each node of the routing path of a communication is encrypted utilizing an identity-based encryption scheme. This allows each node of the routing path to decrypt only those portions of the routing path necessary to send the communication to the next node. Thus, each node will only know the immediate previous node from which the communication came, and the next node to which the communication is to be sent. The remainder of the routing path of the communication, along with the original sender and intended recipient, remain confidential from any intermediate nodes in the routing path. Use of the identity-based encryption scheme removes the need for significant key management to maintain the encryption/decryption keys.
