In recent years, several anonymous routing protocols for wireless ad hoc networks have been proposed. In 2007, Lu, Cao, Wang and Sun proposed a secure routing protocol with anonymity property and key exchange for ad hoc networks. However, in this paper, it is demonstrated that the so-called secure, anonymous key exchange protocol introduced by Lu et al. is vulnerable to a passive attack and, as a result, the anonymity property of the protocol may be compromised. A simple improvement is suggested to eliminate the vulnerability.
