Abstract :
The cloud computing environment offers numerous benefits and different flavours of data storage patterns, which completely relieves the users from the annoying processes of data management, storage equipment upgradation and so on. However, the major concern of the users is the data security and to combat with it several security based solutions are presented in the literature. This article presents a time conserving cloud data storage solution based on keccak and Elliptic Curve Cryptography (ECC) with minimal storage overhead. The proposed work applies LZ77, which is a lossless compression algorithm on the data to be outsourced and then the proposed algorithm is applied. This work does not employ any third-party agent for tracking the data security, as the third party is not completely trustworthy. Hence in this approach, the cloud users apply the proposed algorithm before the process of outsourcing and this approach withstands data analysis and data tamper attacks. Additionally, the proposed work consumes minimal time for execution, which in turn reduces the energy consumption as well. The performance of the proposed work is effective, when compared to the existing algorithms.
