补充资料：《保密系统的通信理论》
C.E.仙农关于信息论的一篇著名论文，发表在《贝尔实验室技术杂志》第28卷第4期(第656～715页),1949年。仙农在这篇论文中，对他在1948年发表的经典论文《通信的数学理论》中所创立的信息论的概念和方法作了进一步发挥，并精辟地阐明了关于密码系统的分析、评价和设计的科学思想。本文提出了保密系统的数学模型、随机密码、 纯密码、 完善保密性、理想保密系统、唯一解距离、理论保密性和实际保密性等重要概念，并提出评价保密系统的5条标准,即保密度、密钥量、加密操作的复杂性、误差传播和消息扩展。这篇论文开创了用信息理论研究密码的新途径，一直为密码研究工作者所重视。它不仅是分析古典密码（如单表代换和多表代换密码）的重要工具，而且也是探索现代密码理论的有力武器。文中所提出的破译密码的计算量理论已和计算机理论中的计算复杂性理论结合起来，成为评价密码安全性的一个重要准则。
