保密增强在无条件安全密钥协商中的应用

Application of Privacy Amplification to Unconditional Secure Secret - Key Agreement

介绍了保密增强的概念,并研究了它在无条件安全的密钥协商中的应用。最后,以Renyi熵为测度,定量地分析了保密增强所能提取出的秘密钥长度与窃听者所掌握的信息间的关系。

This paper introduces the concept of privacy amlification, and studies the application of privacy amplification to unconditional secure secret - key agreement. At last, the relation between the length of the secret- key that can be distilled and the information known by the eavesdropper is quantified with the help of Renyi entropy as measurement method.
