Short digital signatures are essential to ensure the authenticity of messages in low-bandwidth communication channels and are used to reduce the communication complexity of any transmission. A new short signature scheme based on the bilinear pairing in the standard model is introduced. The proposed scheme has short public parameters and the size of the signature achieves 160 bits. In addition, under the
-Exponent Computational Diffie-Hellman Problem(
-CDH), the new scheme is provable security. To the best of authors knowledge, this is the first scheme whose signature size achieves 160 bits based on the bilinear pairing.
