Paper Abstract

Ekert91 protocol of quantum key distribution is an important protocol of key distribution that based on the quantum mechanics. According to it, we first discuss the variance functions of Bell inequality test and error rate comparison, and then define the sensitivities of two security strategies based on Bell inequality test and error rate comparison respectively. Finally we give out the eavesdropper's optimal attack strategy and compare the sensitivities of two security strategies.
