Real-time cheat-free gaming on the basis of time-stamp service
A cheat-proof protocol for real-time gaming is proposed under
the assumption that time-stamp servers issue serially numbered
time stamps honestly and are available near every player, i.e.,
they exist everywhere in the Internet. With this protocol, each
player sends its action to the other player and also sends its hash
to the nearest time-stamp server. The time-stamp server sends the
signed hash with the time and a serial number back to the player.
The actions are checked to verify that they are compatible with
the hashes, and the signed hashes are checked to verify that they
have the correct time and the serial numbers are contiguous. The
only latency in this protocol is the travel time of the packet from
one player to another. In comparison with other existing
protocols, we confirm that the proposed protocol is as fast as and
more secure than the fair synchronization protocol, the fastest
existing protoco
