Abstract :
Anonymous communications in mobile ad hoc networks is an important and effective way against malicious traffic analysis. Various anonymous routing schemes have been proposed for MANETs. However, most works failed to resist the global tracker, and always ignored the reliability of data delivery. In this paper, a comprehensive anonymous communication protocol, called ARSC, is proposed. The ARSC consists of anonymous routing, which is based on identity-based encryption pseudonym and single-round onion, and secure checking of traffic forwarding in data transmission phase, to achieve strong route anonymity and improve reliability of packet delivery in the data transmission phase. From the security analysis, our protocol ARSC is more secure than other schemes such as ANODR, SDAR, AnonDSR, CAR and MASK. Moreover, simulation experiments show that the ARSC has better performance than any other onion-structured anonymous routing protocols.
