Hierarchical access control system for mobile cloud computing
(0) Based the traditional Attribute-Based Encryption (ABE) access control systems, this paper first proposes a new access architecture for MCC, which introduces a middle layer sitting between mobile devices and their cloud infrastructure.This middle hyer is composed of cloudlets and thus it is called access cloudlet layer.Cloudlets are deployed next to IEEE 802.11access points (APs) and serve as a localized service point at a mobile devices close proximity to improve the performance of mobile cloud services.On top of this new architecture, an ABE access control scheme is proposed to offload the main amount of computations to the cloudlet as the function of cloud, in which the access control decision making takes into consideration energy consumption of access task execution and network status while satisfiying certain response time constraints.Then the analysis results have shown the effectiveness and efficiency of the proposed system architecture in terms of security and energy consunption.
