A Study on Data Security and Privacy Issues in Cloud Computing

Cloud computing is an emerging field due to its high performance, high availability, and low cost. The cloud offers numerous services. Cloud services major use case is data storage. Cloud provides to the customer massive amounts of storage capacity. However, many cloud providers are still hesitant to implement cloud computing technology due to an inadequate security policies and protection measures, which leads to numerous challenges in cloud computing. The goal of this survey is to identify the different cryptographic algorithms eventually ensure the cloud highly secure. The main objective of this survey is to prevent unauthorized data access and to provide data security in the cloud by proposing a homomorphic encryption algorithm.
