Wang C, Shi D, Xu X - PLoS ONE (2015)

Bottom Line: Our main approach is to use our improved AMRIBE scheme and improved IBOWAKE protocol in onion routing circuit construction.Compared with other onion routing protocols, AIB-OR provides high efficiency, scalability, strong anonymity and fault tolerance.Performance measurements from a prototype implementation show that our proposed AIB-OR can achieve high bandwidths and low latencies when deployed over the Internet.

ABSTRACT
The rapid growth of Internet applications has made communication anonymity an increasingly important or even indispensable security requirement. Onion routing has been employed as an infrastructure for anonymous communication over a public network, which provides anonymous connections that are strongly resistant to both eavesdropping and traffic analysis. However, existing onion routing protocols usually exhibit poor performance due to repeated encryption operations. In this paper, we first present an improved anonymous multi-receiver identity-based encryption (AMRIBE) scheme, and an improved identity-based one-way anonymous key agreement (IBOWAKE) protocol. We then propose an efficient onion routing protocol named AIB-OR that provides provable security and strong anonymity. Our main approach is to use our improved AMRIBE scheme and improved IBOWAKE protocol in onion routing circuit construction. Compared with other onion routing protocols, AIB-OR provides high efficiency, scalability, strong anonymity and fault tolerance. Performance measurements from a prototype implementation show that our proposed AIB-OR can achieve high bandwidths and low latencies when deployed over the Internet.

pone.0121226.g004: Comparison of Onion Packet Size.

Mentions: For PB-OR, the size of onion packets becomes larger with the increase in the number of onion routers. For the intermediate routers, the closer to the destination node, the higher bandwidth overhead will be. There is no such problem in our AIB-OR. Fig. 4 shows the comparison of onion packet size in PB-OR [10] and in our AIB-OR. As shown in the figure, the size of onion packet in our AIB-OR is shorter than in PB-OR. Moreover, the growth rate of onion packet size in our AIB-OR is slower than in PB-OR.
