Enhancing Privacy and Security in Cloud Computing Using the Covenant Code Exchange

Abstract

This paper proposes a model for enhancing privacy and security in cloud computing known as the Covenant Code Exchange (CCE). The model is proposed as part of the Service Level Agreement (SLA) for cloud providers and users as well as a third party (a witness). In particular, the model we propose allows a cloud provider, user and a witness to exchange covenant codes during transactions to ensure privacy, security and accountability. The covenant code exchange (CCE) requires the code of all parties that are involved for a successful transaction. A key feature of the proposed model is that a transaction cannot be completed with the codes of all parties concerned. Our model is very e cient and effective; when compared to other models; certi cation, accreditation, authorization and authentication, it involves a transaction cannot be completed until all parties have exchange of covenant codes. Additionally, when there is a breach in security, all parties will be held accountable. This ensures that each party is critical and cautions before, during and after a transaction is successfully executed
