A framework for dynamic access control system for cloud federations using blockchain

Abstract

A cloud federation is a network of cloud computing environment consisting of two or more providers. In this framework, the user classification is done dynamically depending on their user’s blockchain transactions. The data classification is done in the cloud using the suitable methods. The data access from the cloud will be given to the users who have the access or permission to use the data depending on their access/privilege rights. For the new user, the access will be through voting based on the new users from different organizations. The votes are given by the trusted parties, and their votes are valid only after their blockchain transaction verification. For a new user to access the data, he requires minimum of votes from the trusted parties.
