Multi-authority Electronic Voting Scheme Based on Elliptic Curves
C. Porkodi, R. Arumuganathan, K. Vidya · 2011
In this paper, a new multi authority electronic voting scheme based on elliptic curves is proposed. According to the proposed scheme, each voter casts the vote as a point on the elliptic curve and the final tally is computed with the assistance of multiple authorities. A trusted center is involved in the scheme to distribute the shared secret key among the authorities and the Shamir (t, n) thresh-old scheme is used for key distribution. The proposed scheme also meets the essential requirements of e-voting system. Ultimately, the proposed voting scheme fortifies the security properties of the electronic voting procedure, since the secrecy of the particularized vote is preserved by ElGamal cryptosystem and Elliptic curve discrete log-arithm problem.
