Abstract Techniques which can realize anonymity play an important role in the protection of partners’ privacy. Sign-cryption can sign and encrypt message in one logic step and has lower cost than that of "firstly sign and then encrypt". Based on the thoughts of Diffie-Hellman decision problem and anonymous signature, an unconditionally anonymous sign-cryption algorithm is given in this paper.
