And lattices has elevated it to the status of a promising potential alternative to cryptography based on discrete log and factoring, owing to implementation simplicity, provable security reductions and quantum-immune. In this paper, the first lattice attribute-based signature scheme in random oracle ...

Attribute-based group signatures allow a group member who possesses certain attributes to anonymously sign messages on behalf the group, and an opening authority can reveal the real identity of the signer from a signature in case of any needed. Almost all of the existing schemes work only in ...

Based on this consideration, an attribute-based signature on lattices,which could resist quantum attacks, is proposed. This scheme employs "bonsai tree" techniques, and could be proved secure under the hardness assumption of small integer solution problem.上海交通大学学报(英文版)doi:CNKI:SUN:TRAN....
