This paper proposes, for the first time, the use of re-encryption scheme to improve users privacy in a privacy-enhancing system. Firstly, a secure protocol to distribute a re-encryption key from a user A to a service provider B, with the help of n referees, is proposed. Next, this re-encryption key distribution protocol is combined with an existing private credential system to provide a protocol for conditional revocation of private information. This protocol has a strong accountability property with efficient online performance. It does not assume the existence of a single trusted entity. We tolerate up to t dishonest referees (t ≤ n − 1), while A and B are dishonest and do not trust each other.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
