本文证明了Bennett-Bennett（BB84）量子密钥分配协议在信源和检测器处于敌手有限控制下的安全性。这个证明适用于当源和检测器都有小的基础相关的缺陷，这是典型的协议的实际实现。在一些特殊情况下的密钥生成率的估计：发射弱相干态的源，与基相关的效率的检测器，和失调的源和检测器。
This paper prove the security of the Bennett-Brassard (BB84) quantum key distribution protocol in the case where the source and detector are under the limited control of an adversary. This proof applies when both the source and the detector have small basis-dependent flaws, as is typical in practical implementations of the protocol. The estimation of the key generation rate in some special cases: sources that emit weak coherent states, detectors with basis-dependent efficiency, and misaligned sources and detectors.
