Abstract

The signcryption tag-KEM/DEM construction is naturally extended to the ring signcryption in this paper. The security model of hybrid ring signcryption which is constructed by ring signcryption tag-KEM/DEM is given in this paper. A hybrid ring signcryption from lattice theory is proposed which satisfies anonymity and identity authenticity. Moreover, based on the hardness of the learning with errors problem and the short integer solution problem, confidentiality and unforgeability of the proposed scheme is proven in the random oracles model.
