Almost all over IM (Instant Messaging) security schemes either do not provide message authentication and confidentiality protection simultaneously or use sign-then-encrypt method. An efficient signcryption algorithm based on bilinear pairings is proposed in this paper, and an instant messaging security scheme using this algorithm is designed, which reduces communication and computation complexity in comparison with the sign-then-encrypt method. The scheme avoids certificate management, withdrawal and other issues of the PKI public key cryptography, as well as eliminates the key escrow problem of the identity-based cryptography.
