On application of elliptic curves in some electronic voting protocols

Abstract

Electronic voting protocols allow us to carry out voting procedure in which ballots exist only electronically. These protocols provide the secret nature of vote. The main property of electronic voting protocols is the universal checkability, i.e. provision of an opportunity to any person interested, including detached onlookers to check correctness of counting of votes at any moment. In operation cryptography protocols of electronic vote of Shauma - Pederson and Kramera - Franklin - Shoyenmeykersa - Yunga are considered. These protocols are provided on the basis of elliptic curves which application allows us to reduce considerably the sizes of parameters of protocols and to increase their cryptography firmness. Primary benefit of elliptic cryptography is that any subexponential algorithm of the decision of the task of the discrete logarithming in group of points of an elliptic curve is not known at the moment.
