本文通过公共讨论提供了对隐私放大的一般处理，这是 Bennett、Brassard 和 Robert 针对特殊场景提出的概念。隐私放大是一个过程，允许两方从窃听者拥有部分信息的公共随机变量中提取秘密密钥，两方通常对窃听者的信息一无所知，除了满足一定的约束条件外，其结果可应用于无条件安全的秘密密钥协议 协议和量子密码学，它们在窃听和广播频道上产生结果，从而大大加强了保密能力的定义。
This paper provides a general treatment of privacy amplification by public discussion, a concept introduced by Bennett, Brassard, and Robert for a special scenario, Privacy amplification is a process that allows two parties to distill a secret key from a common random variable about which an eavesdropper has partial information, The two parties generally know nothing about the eavesdropper's information except that it satisfies a certain constraint, The results have applications to unconditionally secure secret-key agreement protocols and quantum cryptography, and they yield results on wiretap and broadcast channels for a considerably strengthened definition of secrecy capacity.
