Abstract

In 2008, Das and Joshi proposed a new dynamic program update protocol for wireless sensor networks using the orthogonality principle. Recently, Zeng et at. showed that the Das-Joshi scheme is vulnerable to an impersonation attack and proposed an improved scheme to overcome the weakness. However, in this paper we present that Zeng et al.'s scheme still suffers from the impersonation attacks.
