Abstract : The development of worldwide communications, along with the dramatic increase of computational and storage capacities promise numerous benefits for societies in the years to come. For these systems to develop, security and privacy are necessary. This work presents a novel protocol for privacy preserving network communications, using homo-morphic cryptography. The malleability properties of homomorphic en-cryption allows routing without ever disclosing the sender or receiver of a message, while resisting against basic end-to-end attacks. We first present our protocol in an abstract network model, and instantiate it for ad-hoc networks as a use-case example.
