ID-based Generalized Signcryption without Trusted Party
Caixue Zhou · 2013
GSC(Generalized signcryption) can realize encryption,signature and signcryption with only one algorithm.The formal definitions of identity based generalized signcryption without trusted party and the complete security model were proposed.A concrete scheme was presented by using the bilinear pairings.Its confidentiality and unforgeability were proved in ROM under BDH assumption and CDH assumption.Compared with other ID-based GSC schemes,the new scheme is also efficient.
