(54) Transparent election system with double vote rotation


(57) An Internet election system which consists of two independent servers, wherein the number of the chosen candidate is changed into the number of a different candidate with the aid of a double rotation offset. Both servers have a parameter for this rotation offset which is exclusively known to the respective server and the voter. The identity of the voter is known to the first server, which receives the vote, then converts it to the number of a different candidate by means of the first secret parameter and sends on this number together with an anonymous identification number to the second server. This second server converts this number to the number of the candidate which was chosen by the voter with the aid of the second secret parameter. The second server publishes the chosen candidate together with a verification number which is exclusively known to the second server and the voter, who can verify with this that the vote cast counts. With the original or a replacement polling card, the voter can also vote at a polling place, where a vote cast via the Internet is overwritten or revoked. The votes cast at the polling place can be processed in the same manner as the Internet votes, so that they can be verified as well and the outcome can be calculated.
