【摘要】 本文研究通信双方基于平滑熵在不安全且非认证的公共信道上实现防主动攻击的无条件安全秘密钥的提取 .首先讨论了在不安全且非认证的公共信道上根据部分保密的密钥实现认证的方法 ,然后根据以上方法以抗击敌手在通信双方进行无条件安全秘密钥提取时的主动攻击 ,得出了通信双方以一定概率所协商的秘密钥长度更多还原

【Abstract】 This paper investigates the distillation of unconditionally secure secret key against active adversaries over an insecure and not even authentic channel based on smooth entropy.First we discuss unconditionally secure authentication where the common key is only partially secret,then the authentication method is used to secret key agreement against active opponents and obtains the size of the secret key with some probability.更多还原
