Abstract

The use of cloud environments has been seen to expose major gaps in the traditional access control structures as they current exist, especially in aspects relating to scalability and efficiency. These systems which are effective have a tendency of failing to meet the current needs of the applications. Blockchain solutions that are based on principles including decentralization, transparency, and immutability are highly attractive but limited by scalability. This research project aims to address two fundamental problems from two domains. It replaces an existing traditional access control infrastructure utilized for a standard cloud environment with a decentralized framework which also aims to be comparatively as scalable. All the implementations today utilizing blockchain principles like decentralization, transparency and immutability suffer from lack of scalability. In this project, the framework utilises efficient data flow structures, cleverly distinguishing responsibilities between on-chain and off-chain and most importantly exploring zk-Rollups to enhance response times of a smart contract while not compromising on the integrity and security that a blockchain has to offer. Results demonstrate a framework robust enough to replace a traditional infrastructure handling up to 10,000 requests a second. The above framework also brings down operational costs when compared to traditional models.
