Abstract(in English) | In crowdsensing, many users carrying mobile terminals send environmental data and congestion status to the server together with the user’s location information, and the server analyzes the data to perform environmental monitoring and congestion forecast at the city level. In crowdsensing, in order to realize efficient user authentication with privacy protection, a revocable group signature scheme has been proposed, where the burden on the user side is reduced and the revocation check is performed at high speed. However, in this previous scheme, there is a problem on anonymity, because the number of use of signatures included in the signature leaks. Therefore, in this research, we propose an efficient revocable group signature with the enhanced anonymity. In addition, the practicality is shown by experiments based on implementation on a PC. |
