This paper investigated the possibility of constructing certificateless signcryption schemes using tag-KEM techniques in the certificateless signcryption setting.It could build certificateless hybrid signcryption scheme by combing with DEM.Under the random oracle model,the hybrid signcryption scheme was proved to be secure.The pairings are less a time than that of Li Fa-gen's certificateless hybrid signcryption scheme,and the efficiency is higher.
