%X <p>The theoretical limitation of hacker attack ability and honker defense ability was given. If a hacker wants to successfully beat honker <em>k</em> times, he should have so good skills that he can achieve the purpose with probability arbitrarily close to 1 in the <em>k</em>/<em>C</em> times' offensive; If a hacker achieve <em>S</em> times' real success after <em>n</em> times' attack, there must be <em>S</em>&le;<em>nC</em>. For the honker, if he wants to really successfully defense the hacker for <em>R</em> times, he must have so good skills that he can achieve the purpose with probability arbitrarily close to 1 in the <em>k</em>/<em>C</em> times' defensive; If a honker achieve <em>N</em> times' real success after <em>N</em> times' defensive, there must be <em>R</em>&le;<em>ND</em>. <em>C</em> and <em>D</em> respectively represents the channel capacity of offensive channel and defensive channel. If <em>C</em>&lt;<em>D</em>, the hacker Honker will be losed; If <em>C</em>&gt;<em>D</em>, the honker will be losed; if <em>C</em>=<em>D</em>, it means that they will get considerable strength.</p>
