EFFICIENT ATTRIBUTE BASED MULTIPLE GROUP KEY MANAGEMENT FOR SECURE DOCUMENT ACCESS IN CLOUD SECURITY HEALTHCARE SERVICES

Abstract

The healthcare services are being moved to the cloud processing condition in the ongoing occasions to make them most effective, interoperate and to team up in the exploration and business areas. In spite of the fact that this will upgrade the services offered by the healthcare providers, the vulnerabilities in the security and execution of the open cloud makes the move less operable. And this paper proposed to multiple group key management scheme to diminish the complexities of the archive clients, get to control grid has been presented through which the capacity intricacy is decreased from 0(n) to 0(3) and calculation complexity can be credited to just a single expansion and two subtraction activities. Correspondingly, if there should be an occurrence of a data proprietor, the quantity of subtraction activities has been diminished from 0(n)³ to 0(n) which is the explanation behind decrease in the computational intricacy. Additionally, for the data proprietor, the capacity multifaceted nature acquired is 0(n) as it were. In this way, this work diminishes the overheads caused by both the data proprietors and the cloud clients.
