Cloud computing is a growing paradigm of commercial infrastructure that assures to remove the need for maintaining and handling much expensive computing hardware. As the market develops, the threat to data also grows. Securing the data from unauthorized entrance and ensuring that the data are intact with the proposed scheme solves privacy, integrity, consistency, and unauthorized access problems. This research paper proposed a PHECC hybrid algorithm (Polynomial based Hashing and Elliptic Curve Cryptography) that includes PH with ECC security algorithms to ensure customers their data security in the cloud. In the current scenario, the hybrid algorithm almost guarantees for data security. The efficiency of the proposed technique is compared to other hybrid algorithms.
