摘要

Digital provenance, as an important type of cloud data, has aroused increasing attention on improving system performance. Currently, provenance have been employed to provide hints on access control and estimate data quality. However, provenance itself might also be sensitive information. Therefore, provenance might be encrypted to store on cloud. In this paper, we provide a mechanism to classify cloud documents by searching specific keywords from their encrypted provenance, and we proof our scheme achieves semantic security.
