Improved encryption and obfuscation process of lightweight secured auditable cloud storage with data dynamics

In order to safeguard the cloud-based applications, systems, and user access related to them, several technological solutions, policies, and processes are put forward, termed cloud data security. The term Secure Cloud Storage (SCS) signifies the widely used methods ensuring the security of the data. In contrast to conventional methods, such as a digital signature or Media Access Control (MAC), it is not necessary to consider the total records to validate the data integrity. This work proposes a new Security model in the cloud by guaranteeing the security of data in terms of the Encryption and Obfuscation process, the Lightweight Secured Auditable Cloud Storage with Data Dynamics (LSACSDD). The phase of the suggested work is the Secure Storage Phase: Here, the Improved encryption and Improved obfuscation process-based data security is assured in the storage. Here, Improved Elliptic Curve Cryptography (ECC) is proposed as the encryption process, in which, the optimal key is chosen via Self Improved Beluga Whale Optimization (SI-BWO) model. Outsourcing Phase: Here, three different processes take place, they are auditing, proof and verification. Data Dynamic Phase: It is the final phase, where, the functions of the data dynamics method splits into 2 kinds, the deletion/insertion function and the modification function. Finally, the suggested method is validated over the other methods with respect to different security measures.
