Fine Grained Access Control of Data in Mobile Cloud Computing

Abstract

With the increasing number of mobile applications and the popularity of cloud computing, mobile cloud computing (MCC) attracts great attention in recent years. While using the cloud storage services on resource constraint mobile device, the mobile user needs to ensure the confidentiality of the critical data before uploading on the cloud storage. This paper focused on analysis of five different techniquesType-Based Proxy Re-Encryption, Coding-Based Scheme,Decentralized Attribute Based Encryption (ABE), Ciphertext Policy Attribute-Based Encryption (CP-ABE), A Multi-Authority CP-ABE Scheme. These method contain some issue and drawbacks. To overcome some issue, this paper has proposed Fine-Grained Access Control using Tree Structure scheme.By security analysis and performance evaluation, the proposed scheme is proved to besecure as well as efficient in mobile cloud computing.
