Assume a cryptographic algorithm in which the performance for the good guys (the ones that know the key) grows linearly with the length of the key and for which the only way to break it is a brute-force attack of trying all possible keys. Then, suppose the performance for the good guys is adequate (e. g., it can encrypt and decrypt as fast as the bits can be transmitted over the wire) at a certain size key. Finally, suppose advances in computer technology make computers twice as fast. Given that both parties¾the good guys and the bad guys¾get faster computers, does this advancement in computer speeds work to the advantage of the good guys? The bad guys? Or does it not make any difference?
