基于属性访问策略的批量零知识身份认证方案.

Privacy protection technologies mainly include attribute-based encryption, homomorphic encryption, multiparty security computing, etc. Among them, in the access control of attribute-based encryption, bilinear mapping is time-consuming, homomorphic encryption is difficult to verify the results of plaintext computation in a non-public way,and multi-party security computation requires a trusted third party. To solve these problems, this paper proposed a batch zero knowledge identity authentication scheme based on attribute access strategy. This proposed scheme is based on the Aurora protocol and has good computing potential against quantum attacks. The proposed scheme introduces a synthetic prover to synthesize a proof of the proof generated by each user and reduce the computational cost of the prover and the verifier, and designs a search algorithm to find out unauthenticated users. Finally, this paper carries out safety analysis, feasibility analysis, and comparative analysis with other schemes. After analysis, the verification time in this scheme can be maintained in o (n).
