Implementation of Cloud-Assisted Content Sharing Networks for Scalable Media Using Attribute-Based Access

In this paper, the authors present a novel Multi-message Cipher-text 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, or gender) rather than an explicit list of the consumers' names. Access control is the fundamental security mechanism to facilitate information sharing in a controllable manner. It is challenging to design a suitable access control mechanism in content sharing services. The scheme is efficient and flexible because multi-message cipher text policy attribute-based encryption 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. Cloud computing offers application developers and users an abstract view of services that hides much of the system details and inner workings.
