multi-authority Attribute-based Signature
工程科学与技术, 2011 :In real life, many attributes of a user are monitored by a single authority, which will inevitably increase its workload and reduce its efficiency. In this paper, the proposed multi-authority Attribute-based Signature scheme is that many attributes are ...
