dc.description.abstractOver the past decade, cloud computing security has expanded from a promising secure business concept to one of the fastest-growing segments of the information technology industry. The trend of Open Source Software based cloud computing solutions gets a wide acceptance from the community especially the OpenStack object storage Swift; the Swift widely used. Nevertheless, the security elements with respect to authentication and authorisation, access control and data protection in the existing OpenStack Swift model has various vulnerabilities and weaknesses. This research proposes a robust cloud security model for the OpenStack Swift object storage within cloud computing environment, i.e CloudSecure. CloudSecure is a multi-user based model in which every owner communicate with cloud in a secure channel where each owner is enabled with different levels of security namely CAPTCHA to identify human verification and Blowfish symmetric cryptography for user credentials in the authentication process as well as authorisation process and MD5 hash function is been applied on both sides; the client and the cloud computing server side to verify the data integrity. Moreover, for the selection of the most efficient proxy server from the proxies’ pool, keystone manager in the proposed model implements the scheduler that selected the suitable proxy based on least number of users, available hardware processing, and memory resources. For secure data communication between the client and the servers, a secure channel is been created using RSA (Rivest-Shamir- Adleman) asymmetric encryption to protect sensitive data transmission and storage on cloud. The research focuses on qualitative evaluation comparing new features that makes the proposed model more robust in terms of security. The experiments were conducted in real-time environments by conducting functionality comparison between the CloudSecure model and the OpenStack Swift model. To verify the robustness of the above cryptographic algorithm in proposed CloudSecure model, cryptanalysis is been applied namely Brute force attack against the Blowfish symmetric cryptography and Birthday attacks against the MD5 hash function in the authentication process while Man-in-the-middle (MITM) attacks against the RSA asymmetric cryptographic algorithm on both models; the existing OpenStack swift model and CloudSecure model. A research evaluation is performed to solidify the justification and detailed discussion is conducted to analyse the robustness and reliability of the CloudSecure model in terms of security. In conclusion, the proposed CloudSecure model is more secure and robust as compared to the existing OpenStack Swift model.en_US
