Abstract:
1. A method for processing a communication to be sent from a sending processing device to a destination processing device via a routing path in a network, the routing path including a plurality of intermediate nodes in the network, the method comprising: computing, by a key generating processing device, a respective encryption key associated with each of the plurality of intermediate nodes of the routing path, each of the respective encryption keys being computed based on a public identifier associated with each of the plurality of intermediate nodes and a current date, wherein the public identifier associated with each of the plurality of intermediate nodes is an address of each intermediate node in the network; encrypting, by the sending processing device, only an address of each successive intermediate node of the routing path using the encryption key of each respective previous intermediate node of the routing path and an address of the destination processing device using the encryption key of an intermediate node immediately preceding the destination processing device along the routing path; and sending the communication by the sending processing device, including the encrypted addresses of each of the plurality of intermediate nodes of the routing path, to a first one of the plurality of intermediate nodes.
