A formula that estimates Eve's maximum information when Alice and Bob perform the B92 protocol using two nonorthogonal single-photon polarization states was derived. It was assumed that Alice can emit a single photon and Eve employs individual attack. Using the given formula, the secret key gain as a function of various parameters reflecting intervention by Eve was plotted.
