A Decentralised Mechanism for Secure Cloud Computing Transactions

In this paper, we present an innovative mechanism for transaction processing for big data in Cloud Computing context. We focus on data and information security in proposing the decentralised mechanism. Traditional transaction processing, if monitored, can potentially help an attacker to construct context of the information stored by the client to subsequently determine of value of the client's digital asset. In the proposed mechanism, we take a decentralised and collaborative approach both in terms of implementations and operations of transactions between end-users and Cloud servers. In the proposed transaction mechanism, the total picture of a transaction is not recoverable by unwanted third parties and thus the information on data processed by a transaction may not become a knowledge of an eavesdropper. The proposed mechanism is built upon and motivated by the principles of Ki-Nga-Kopuku - a decentralised and distributed computing security model that employs scattered and redundant decentralised processing.
