The security of the BLS signature scheme is based on the random oracle model. Hence, there is a question that how to instantiate BLS scheme without random oracles. In this work, by using a powerful tool multilinear map, we answer this question. The main contributions of this work are as follows. First of all, we describe the BLS scheme in the setting of multilinear group and prove its security in the standard model. Then, we design a ring signature scheme based on the multilinear BLS scheme. In the proposed scheme, ring signatures consist of a single multilinear group element.
