Abstract: In the original BB84 protocol, the bit basis and the phase basis are usedwith equal probability. Lo et al J. of Cryptology, 18, 133-165 2005proposed to modify the ratio between the two bases by increasing the final keygeneration rate. However, the optimum ratio has not been derived. In thisletter, in order to examine this problem, the ratio between the two bases isoptimized for exponential constraints given Eve-s informationdistinguishability and the final error probability.
