Efficient security solution for privacy-preserving cloud services

In this paper, we present a novel privacy-preserving security solution for cloud services. We deal with user anonymous access to cloud services and shared storage servers. Our solution provides registered users with anonymous access to cloud services. Our solution offers anonymous authentication. This means that users´ personal attributes (age, valid registration, successful payment) can be proven without revealing users´ identity. Thus, users can use services without any threat of profiling their behavior. On the other hand, if users break provider´s rules, their access rights are revoked. We analyze current privacy preserving solutions for cloud services and outline our solution based on advanced cryptographic components. Our solution offers anonymous access, unlinkability and the confidentiality of transmitted data. Moreover, we implement our solution and we output the experimental results and compare the performance with related solutions.
