Abstract |
Cloud computing have high demand due to waste and huge data usage of clients. The privacy and security become major concern on the outsourced cloud data storage. The attribute based encryption schemes are used recently for access control of outsourced cloud data. It has highly inflexible in implementing complex access control policies. The existing work presented Hierarchical attribute set based Encryption (HASBE) that extended cipher-text policy attribute set based encryption (ASBE) with hierarchical structure of users. It used achieve scalability, inherits flexibility, fine grained access control, and employs multiple value assignments for access expiration time, and deal with user revocation efficiently. The performance analysis is made to evaluate the computational complexity of access control for outsourced data in cloud computing. However varying of cloud service provider complicates the hierarchical access control policies. The proposal presented an Adaptive Delegation Authority model enhancement to HASBE. It is used to minimize the complexity of access control policies in changing cloud service provider. The delegation authority coordinates the data owners and consumer for easy and quick data access control. It intimates the data owners and consumers about the authority delegation. The delegation authority sends encryption standards to be followed thereafter. The simulation is carried with Cloud simulator using java to testify in the effectiveness of Adaptive Delegation Authority enhancement to HASBE. |
