基于博弈论的网络空间安全若干问题分析

信息安全经济学是信息安全的一个重要研究领域，博弈论是研究信息安全经济学的主要基础理论和工具之一。基于博弈论对网络空间安全的主要问题进行了分析，其中包括网络攻防、密码协议设计和安全技术配置。对于网络安全攻防，重点分析了攻防双方的对抗状况和防守方之间的互相依赖；对于密码协议设计，重点分析了博弈论在秘密共享和安全多方计算当中的应用；对于安全技术配置，重点分析了博弈论在入侵检测系统和防火墙技术中的应用。最后指出了当前研究存在的不足和信息安全经济学未来的研究方向。

Analysis of cyberspace security based on game theory

Information security economics is an important research area and game theory is one of the main basic theories and tools of cyberspace security.Based on game theory,the main problems of cyberspace securing were analyzed which including network attack and defense,cryptographic protocol design,and security technology con-figuration.The conflicts between attackers and defenders as well as the dependence among defenders were mainly analyzed on network and defense.Game theory’s applications in secret sharing and secure multi-party computation were emphasized on cryptographic protocol design.The game theory’s applications in intrusion detection system and firewall technology were analyzed on security technology configuration.Finally,the limitations of current re-searches and carries on the forecast to the future research directions were pointed out.
