Abstract Generalized signcryption is a cryptographic primitive which could not only realize signcryption but also provide encryption and authentication alone. In this paper, the formal definition and a complete security notion of identity based generalized signcryption for multiple PKGs is defined. A concrete scheme is also proposed with security proof in standard model. Compared with several existing identity based signcryption schemes for multiple PKGs, the new scheme is more efficient and flexible.
