A Cost-effective 2-tier Security Paradigm to Safeguard Cloud Data with Faster Authentication: A Recent Study

Recent technological advancements have elevated cloud computing (CC) infrastructure to a significant level, with increasing research focus on cost-effective storage management. It lacks efficiency in fully preserving the integrity of user data attributes due to the potential distributed and pervasive storage facility. As a result, the collaborative sharing of user data creates a situation that opens up various types of security loopholes. In the cloud, consumer’s data are obtained to cloud service providers which can be trusted or untrusted. Various forms of security protocols have been observed in the past that attempted to solve this similar issue with cryptographic solutions but lacks sustainability and robustness from a computational standpoint. As a result, the study introduces a 2-tier framework that provides a higher level of access control as well as Virtual Machine (VM) storage security. The study basically optimizes the model's performance by speeding up the authentication process. The system's performance has been validated in relation to conventional encryption standards. The results show that the proposed solution outperforms existing security standards in terms of processing time, time to generate a secret key, and key size for encryption.
