Certificateless generalized signcryption

Ji Huifang, Han Wenbao, Zhao Long

Abstract: Generalized Signcryption is a fresh cryptographic primitive that not only can obtain encryption and signature in a single operation, but also provives encryption or signature alone when needed. This paper gives a formal definition of certificateless generalized signcryption and its security model is present. A concrete certificateless generalized signcryption scheme is also proposed in this paper.
