摘　　要：理论意义上安全的密钥分配协议是近几年研究的热点,已经研究多时的量子密钥分配协议也可以归结为理论意义上安全的密钥分配协议。一旦理解了它,就可以从更高的角度来理解量子密钥分配协议。它也提出了如何用经典的办法来达到量子密钥分配的安全性以及其局限性。现就理论意义上安全的密钥分配协议进行了总结。Information-theoretical security secret key agreement protocol has become hot in recent years. QKD could also be included into it. If people thoroughly understand it, they can know more about QKD from a higher level. It also reveals the security and limitations of the way using classical key distribution. This paper summarizes the all points in the information-theoretical security secret key agreement protocol （ITSSKP）.

关 键 词：理论意义上安全的密钥分配协议 数据筛选 协商过程 保密增强
