A cryptographic protocol useful in electronic voting, invented by Pascal Paillier in 1999. A vote for a candidate (1 = for, 0 = against) is blinded through multiplication by a power of a large random number) and then encrypted using Paillier's protocol. The protocol has the property that the votes of all the voters (each of which is secret because of the randomization factor), when multiplied together and then decrypted, yield the total number of votes for the candidate. The protocol can be used for VERIFICATION. END-TO-END
