### Paper: Provable Secure Generalized Signcryption

Authors: Xu-an Wang Xiaoyuan Yang Yiliang Han URL: http://eprint.iacr.org/2007/173 Search ePrint Search Google Generalized Signcryption is a new cryptographic primitive which can work as an encryption scheme, a signature scheme or a signcryption scheme. We give security notions of Generalized Signcryption and improve a Generalized Signcryption scheme proposed by Han et al.We give the formal attacking model of this new cryptographic primitive in the framework of theory of provable security. At last, we give formal proofs for this new improved Generalized Signcryption in our attacking model.
