摘　　要：An attribute-based ring signature scheme in lattice was proposed in this paper. In this signature scheme, an entity’s attributes correspond to the columns of a lattice matrix, and the signature was generated by using a subset of these attributes. The entities possessing these attributes form a ring. The scheme is computationally efficient than the schemes based on the integer factor problem and discrete logarithm problem, furthermore it is still secure in quantum computing environment.An attribute-based ring signature scheme in lattice was proposed in this paper.
