    "abstract": "We prove the security of the 1984 protocol of Bennett and Brassard (BB84) for\nquantum key distribution. We first give a key distribution protocol based on\nentanglement purification, which can be proven secure using methods from Lo and\nChau\u0027s proof of security for a similar protocol. We then show that the security\nof this protocol implies the security of BB84. The entanglement-purification\nbased protocol uses Calderbank-Shor-Steane (CSS) codes, and properties of these\ncodes are used to remove the use of quantum computation from the Lo-Chau\nprotocol.",
