Secure and efficient ID-based generalized signcryption scheme
安全高效的基于身份的广义签密方案

This paper proposed a new secure and efficient ID-based generalized signcryption scheme using the bilinear pairings.Its confidentiality and unforgeability were proved in ROM under BDH assumption and CDH assumption.Finally,analyzed the efficiency of the scheme.It shows that the scheme has higher efficiency.
