I guess we should pay more attention to the real motivation of the players. In my opinion it is very unlikely that attackers want to "maximize economic pain" of the defender, it is more believable that they simply want to be the first to solve the challenge. If it is a good approximation, then the best strategy is to release the keys as fast as possible. It is not obvious what the defender's motivation is: despite their claims (do they believe themselves?) it seems unlikely that DVD sales are significantly affected by availability of the decryption keys or the ripped content. I guess the only problem they have is the embarrassing situation due to PR. If it is a good approximation, then likely the best strategy is to revoke keys a couple of times to make public less interested and pretend that everything is OK. -- Regards, ASK --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
