<p>PURPOSE: To enable an outside observer to verify whether or not an election is carried out actually correctly by sequentially processing ciphered messages from senders at a mixing center and outputting a group of messages which are ciphered in random order wherein they can not be traced finally. CONSTITUTION: Voters vote through senders 10(1), 10(2)... equipped with arithmetic means, suitably, personal computers. Similarly, respective mixing centers 11(1), 11(2)... are equipped with arithmetic means, suitably, personal computer, work stations, etc. Then the senders 10(1), 10(2)... report voter's ciphered messages firstly to an electronic bulletin board 12 or other openly usable message means. A center 11(i) processes respective messages reported by a preceeding center 11(i-1) and makes the results in shuffled order. This is carried out until the final center 11(n) makes the totalization result of the voting open to the public.</p> |
