Query: Effect of Transmission Loss on The Fundamental Security of Quantum Key
  Distribution   It is shown that the effect of transmission loss has often not been properly
taken into account in the security proofs on quantum key distribution. A class
of general attacks to be called probabilistic re-sends attack is described that
has not been accounted for, which is a generalization of the well-known unique
state determination attack. In the case of the four-state single-photon BB84
protocol, it is shown in detail how such attacks are not accounted for in the
known security proofs against the simplest individual attacks.
