Security Weaknesses in Two Certificateless Signcryption Schemes

S.Sharmila Deva Selvi and S.Sree Vivek and C.Pandu Rangan

Abstract

Recently, a certificateless signcryption scheme in the standard model was proposed by Liu et al. in \cite{LiuHZM10}. Another certificateless signcryption scheme in the standard model was proposed by Xie et al. in \cite{WZ09}. Here, we show that the scheme in \cite{LiuHZM10} and \cite{WZ09} are not secure against Type-I adversary.
