In 2011, Abhijith Das et al. [1] proposed a protocol based on hierarchical model for node authentication in group communication in VANETs and claimed that their protocol is robust against conventional security attacks. In this paper we will show that Abhijith Das et al. [1] scheme cannot withstand to various conventional security attacks and fails to provide authentication. We then present our improved scheme.
