Mobile Peer-to-Peer Networks (MOPNETs) in Wireless Mobile Ad Hoc Networks (MANET) have become very popular applications due to their easy communication and resource sharing patterns in unfixed network infrastructures. As privacy and security is coming under increasingly attention, many MANENT protocols attempt to provide mutual anonymity for users. Most existing anonymous designs, however, are path-based, where the anonymous communications are achieved via pre-determined path. Such a design suffers from unreliable delivery and high processing overheads, and is not practical. We propose a scalable secret-sharing-based mutual anonymity protocol, termed PUZZLE, which enables anonymous query issuance and file delivery for MOPNETs in ad hoc environments by employing a Shamirs?? secret sharing scheme. We present the design of PUZZLE, analyze its degree of security and anonymity, and evaluate its performance by comprehensive trace driven simulations. Experimental results show that, compared with previous designs, PUZZLE achieves mutual anonymous communications with a low cryptography processing overhead and high degree of anonymity.
