With the growth of technology everything is controlled by our fingertips. Each and every important and confidential data is shared over cloud. Cloud computing is where our data is kept, computed and handled and they are provided by different service providers like Amazon, Google, etc known as CSP(Cloud Service Provider). Security is a bigger area of concern here as we cannot ignore any risk regarding our confidential sensitive data. So we proposed a model of Hybrid Homomorphic Encryption which focuses on building a model in which the operations are carried on the encrypted data and getting the desired result without any need to decrypt the data. The model uses a combination of two encryption algorithms that can perform some basic mathematical operations, they are:
•RSA algorithm is used to achieve partial multiplicative homomorphism.
– By simple power function
– By successive modulus
– By Modulus Exponentiation
•Paillier’s algorithm is used to achieve partial additive homomorphism.
