摘要
Cloud computing is emerging as an increasingly popular computing paradigm. Sharing of data in the cloud environments raises the issues of confidentiality, integrity, and availability. In this paper, we propose a framework and methodology for sharing data over untrusted cloud, using proxy re-encryption based on elliptic curve discrete logarithm problem. The proposed methodology imperatively imposes the access control policies of data originator, preventing the cloud storage providers from unauthorized access and illegal authorization to access the data.
