Abstract:-Large amount of data is generated in today's world. Saving that data on a single machine is a critical task, so the best way is store that data on the cloud. Cloud computing helps us to acquire data storage, resources over the internet. As far as considering internet, security becomes a major concern .To provide the security for the data stored on the cloud Homomorphic encryption plays major role. It allows cloud to perform calculation on the data. Cryptosystem based on Residue Number System and Secret Sharing Scheme can have disadvantage that it leads to data redundancy which in turn increases the storage size. To overcome the disadvantage considering one of the applications of Homomorphic encryption that is “Online Voting System†where we can provide security by combining cryptosystem and arithmetic coding. By using this mechanism we can directly encrypt and decrypt data on cloud.
