An Efficient Anonymous Routing Protocol Without Using Onion Technique in MANET
Sung-Yun Lee, Heekuck Oh, Sang-Jin Kim · Information Security and Cryptology · 2009
There have been a lot of researches on providing privacy in MANET (Mobile Ad hoc NETwork) using trapdoor, onion, and anonymous authentication. Privacy protection in MANET can be divided into satisfying ID privacy, location privacy, route privacy, and unlinkability between sessions. Most of the previous works, however, were unsatisfactory with respect to location privacy or route privacy. Moreover, in previous schemes, cryptographic operation cost needed to meet the privacy requirements was relatively high. In this paper, we propose a new efficient anonymous routing protocol that satisfies all the privacy requirements and reduces operation costs. The proposed scheme does not use onion or anonymous authentication techniques in providing privacy. We also provide a more accurate analysis of our scheme's efficiency by considering all the nodes involved in the route establishment.
