    "abstract": "We prove that BB84 protocol with random privacy amplification is secure with\na higher key rate than Mayers\u0027 estimate with the same error rate. Consequently,\nthe tolerable error rate of this protocol is increased from 7.5 % to 11 %. We\nalso extend this method to the case of estimating error rates separately in\neach basis, which enables us to securely share a longer key.",
