Data can be easily accessed from anywhere when resources are shared across an insecure network in the cloud due to security concerns with respect to confidentiality, authenticity, and integrity. Security and privacy issues develop concurrently for a variety of reasons, including data security, a lack of data confidentiality, etc. Growing demands of resources and development of new technology are the reason for the open and shared data storage. Thus, the safe data storage services in a cloud environment are required for this criterion. The service provider is not the trusted provider in the public cloud environment. The method employed in the proposed study assumes the usage of homomorphic encryption together with the ECC and RSA algorithms. A comparison between RSA and ECC is used to improve security.
