Abstract: In this paper, we present attribute-based ring signcryption scheme, which realizes the concept of ring signcryption in the attribute-based encryption frame firstly. In our system, it allows a user to signcrypt a message by a set of attributes that are chosen without revealing its identity. In additional, we propose the security models and prove the confidentiality and unforgeability of our schemes. We also present the efficiency of our scheme by comparisons.
