摘要
描述了证明量子密码学无条件安全性的基本技术。它们被应用于 Bennett 和 Brassard 于 1984 年提出的量子密钥分发协议。该证明考虑了协议的一个实际变体，其中信道有噪声且光子可能在传输过程中丢失。对信道的初始编码必须完美（即，与该协议中所描述的完全一致）。除了接收到的系统是否被探测必须独立于用于测量该系统的基之外，对信道接收端所使用的探测器不加限制。

备注
Version 5: This is an improved version of the paper that was published in JACM. Previous version: Revtex 18 pages. An appendix which summarizes the notations was added. As in the previous version, the proof uses the POVM model to prove the security of quantum key distribution against all attacks. The proof assumes a noisy channel and an imperfect measuring apparatus
