The invention pertains to a method and system for verifying election results, in association with an election process and a particular election. One useful embodiment of the invention is directed to a method, wherein a plurality of voters are each authorized to cast a ballot by using a specified voting device of a voting system, wherein the specified device may have one of a number of states, and the process is under the supervision of an Election Authority (EA). The method includes the step of publishing a number of certificates, wherein each certificate corresponds to one of the specified device, and contains one or more public keys associate with its corresponding device and also contains an Election Configuration (EC) that indicates the expected state of its corresponding device during the election process. The method further includes generating a voter authorization token (VAT) for each authorized voter, wherein each VAT enables one of the authorized voters to anonymously cast only one of the ballots in the particular election. A set of voting results is generated in response to the use of a given one of the VATs to cast a given ballot, wherein the set of voting results includes the given VAT, the cast given ballot, and the state of the voting device when the given ballot was cast. The set of voting results is also signed by a unique private key that corresponds to one of the public keys that is associated with the specified voting device. A further step of a method comprises publishing a set of items that include at least lists of all VATs and all sets of voting results that are respectively generated in connection with the particular contest, wherein the published items are available, together with the published certificates, for use by members of the public to verify election results.
