session keys in an online e-voting system Server1 can just generate a large random number as token and send a list of valid tokens to Server2. Alternatively Server1 can use a HMAC. Please note that this is voting scheme in not in compliance with the requirements of democratic elections for multiple reasons: The voter cannot prevent Server1 and Server2 from cooperating to reveal his vote. Furthermore a voter cannot verify that the counted votes match the actual votes. |

session keys in an online e-voting system The idea behind this concept is to have server1 verify the identity of the person in order to prevent a voter from voting twice. In a real election, this is done by the voting committee. Server1 hands out a token that can be used to vote exactly once, like the empty piece of paper on which you mark your vote. Server2 accept the token and the vote, like the ballot-box. |
