Abstract
We analyze the asymptotic key rate of the single photon B92 protocol by using Renner´s security analysis given in 2005. The new analysis shows that the B92 protocol can securely generate key at 6.5% depolarizing rate, while the previous analyses cannot guarantee the secure key generation at 4.2% depolarizing rate.
