In each round of the game Magnus chooses the number of positions for the token to move, and Derek decides in which direction, + (clockwise) or − (counterclockwise), the token will be moved. Magnus aims to maximize the total number of position...

However, with the emergence of quantum computers an adversary may have no difficulty in breaking known cipher systems. If quantum computers would exist today new mechanisms for security would need to be built. ...
