Abstract

This paper shows that the BB84 protocol with random privacy amplification is secure with a higher key rate than Mayers´ estimate with the same error rate. Consequently, the tolerable error rate of this protocol is increased from 7.5% to 11%. We also extend this method to the case of estimating error rates separately in each basis, which enables us to securely share a longer key
