A New Protocol For Strong Coin Tossing
Roger Colbeck · CERN Document Server (European Organization for Nuclear Research) · 2006
In the literature, strong coin tossing protocols based on bit commitment have been proposed. Here we examine a protocol that instead tries to achieve the task by sharing entanglement securely. The protocol uses only qubits, and has bias 1/4. This is equal to the best known bias for bit commitment based schemes.
