Data security is one of the crucial tasks for any information that is stored in the cloud server. Many cryptographic algorithms have been in existence but still are prone to various types of attacks. The major functionality for a cryptosystem is to prevent from various attacks from learning messages which are confidential. Cryptography plays an important role in data transmission and protecting the network. It also prevents reading private messages from third party. The cloud security involving

It enables us to provide results of calculations on encrypted data without knowing the raw data on which the calculation was carried out. It maintains data privacy and confidentiality. This paper focuses on the performance analysis of different homomorphic encryption algorithms. The algorithms include Modified RSA (MRSA), RSA, Hybrid homomorphic encryption and hill cipher with respect to homomorphic encryption. A comparative study is carried with the above algorithms and it is clear that MRSA is more efficient and secure than others.
