Abstract:

Anonymous heterogeneous signcryption scheme can not only transfer data confidentially for users in heterogeneous cryptographic environment,but also provide privacy protection for users of both sending and receiving sides.The security of an anonymous heterogeneous signcryption scheme was analyzed and that it did not satisfy confidentiality and anonymity was pointed out.A new MAHSC (mutual and anonymous heterogeneous signcryption) scheme was proposed.It was analyzed that its security satisfied the confidentiality of messages,the unforgeability of signatures and the anonymity of sender’s identity.The results of efficiency and security analysis show that the proposed scheme is feasible.

Key words: heterogeneous signcryption, anonymous signcryption, q-Diffie-Hellman inverse problem
