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.
