This invention provides a method for transferring third party landing based on IP network including: a door network station carries a ciphered KEY generated randomly by a service server to send a link request to a third party network station so as to avoid transmission of user ciphered codes and ensure absolute security of user codes, besides, since the third party network station calls back the Web server by copying the ciphered KEY to verify the cryptographic key so as to secure the absolute safety of shaking hands, since the door network station does not transfer user ciphered codes with the third party network station, which is not necessary to synchronize with the door station about codes, thus the requirement of complicated maintenance to synchronization on ciphered codes to the third party is reduced.

本发明提供了一种基于IP网络转接第三方登陆的方法，其关键是，由门户网站携带业务服务器随机生成的加密KEY向第三方网站发送链接请求，避免了用户密码的传输，因而保证了用户密码的绝对安全性。再有，由于第三方网站通过复制加密KEY回调Web服务器，由Web服务器进行密钥验证，因而又保证了握手的绝对安全性。应用本发明，由于门户网站与第三方网站之间不传递用户密码，使得第三方网站无需与门户网站进行密码同步等机制的处理，在大大提高安全性的同时，降低了对第三方网站对于密码同步机制等复杂维护的要求。
