Light Blue Touchpaper previews a paper [PDF] describing the Open Vote Network protocol that would allow anonymous voting under a system of total communications surveillance. “In the Open Vote Network protocol, all communication data is open, and publicly verifiable. The protocol provides the maximum protection of the voter’s privacy; only a full collusion can break the privacy. In addition, the protocol is exceptionally efficient. It compares favorably to past solutions in terms of the round efficiency, computation load and bandwidth usage, and has been close to the best possible in each of these aspects.“
