| 摘 要： | 本文讨论了通信双方在公共信道上基于平滑熵进行无条件安全秘密钥协商协议来提取秘密钥时,窃听者在信息协调阶段获得的边信息对保密增强阶段所能提取出的秘密钥长度的影响,得出了以一定概率所协商的秘密钥长度.

| Abstract: | This paper investigates the effect of side-information,obtained by the opponent through an initial reconciliation step,on the size of the secret-key that can be distilled safely by subsequent privacy amplification in uncoditionally-secure secret-key agreement protocol based on smooth entropy,and obtains the size of the secret-key with some probability. |

| Keywords: | smooth entroy secret-key agreement information reconciliation privacy amplification |
