An attribute based signature scheme from lattice assumption
Inspired by the framework of Boyen, in this paper, an attribute based signature (ABS) scheme from lattice assumption is proposed. In this attribute based signature scheme, an entity's attributes set corresponds to the concatenation of a lattice matrix with the sum of some random matrices, and the signature vector is generated by using the Preimage Sampling algorithm. Compared with current attribute based signature schemes, this scheme can resist quantum attacks and enjoy shorter public key, smaller signature size and higher efficiency.
