In an electronic voting process, a voter (Vi) encrypts his vote (vi) according to the encryption scheme (ETM) of a tallier mix-net (50) used to tally up the votes cast. The voter (Vi) obtains on his encrypted vote, (xi), from an admin server module (20), a digital signature according to a fair blind signature scheme (FBSS). The encrypted vote (xi) is encrypted a second time, together with the unblinded digital signature (yi) thereof by the admin server, using the encryption scheme (EM) of a randomizing mix-net (40), to yield an output (ci), and the voter uses his own signature scheme (Si) to sign this, giving (σi). The voter sends an ID code and data including (ci,σi) to a bulletin board server (30). Discrepancies in this vote data can be detected and their origin traced by prompting the randomizing mix-net servers (40) to provide proofs of correctness, and using the signature-tracing mechanism of FBSS.
An electronic voting method comprising the step of using a fair blind signature scheme to obtain a digital signature (yi) of a data signal (xi) comprising a voter's vote (vi).
An electronic voting system comprising:
A voter module (10) adapted to cooperate with an admin server module (20) in application of a fair blind signature scheme whereby to obtain a digital signature (yi) of a data signal (xi) comprising the voter's vote (vi).
A voting system admin server module (20) adapted to cooperate with a voter module (10) in application of a fair blind signature scheme whereby to obtain a digital signature (yi) of a data signal (xi) comprising the voter's vote (vi).
A voting system randomizer module (40) comprising:
A voting system tallier module (50) comprising:
