AN ACCESS CONTROL SCHEME FOR SCALABLE MEDIA CONSUMERS IN CLOUD-ASSISTED CONTENT SHARING NETWORKS

In this paper presents a novel Multi-message Ciphertext Policy Attribute-Based Encryption (MCP-ABE) technique, and employs the MCP-ABE to design an access control scheme for sharing scalable media based on data consumers' attributes (e.g., age, nationality, gender) rather than an explicit list of the consumers' names. The system is efficient and flexible since MCP-ABE allows a content provider to specify an access policy and encrypt multiple messages within one cipher text such that only the users whose attributes satisfy the access policy can decrypt the cipher text. furthermore, the paper organizes how to support resource-limited mobile devices by of loading computational intensive 10 operations to cloud servers while without compromising data privacy.
