Secure Cloud e-Voting System Using Fully Homomorphic Elliptical Curve Cryptography

e-Voting system simplifies the traditional voting process from the point of view of both the voters as well as the officials. Voter turnout increases as the voting become more easy and convenient. The expense for human resources is drastically reduced as counting and tallying are all done by the software itself. Homomorphic Encryption (HE) is a cryptographic method which supports the processing of data while it is in encrypted form. In this paper, a cloud e-Voting system is implemented using Fully Homomorphic Elliptical Curve Cryptography (FHECC). This ensures that privacy is preserved and the risk of the vote being tampered or leaked is minimum, even if the votes are stored in the public cloud. This paper also analyses the implementation of FHECC and compares it with older and widely used homomorphic algorithms like ElGamal cryptosystem and Paillier cryptosystem and the study shows that FHECC has better performance and improved security.
