摘要:

访问控制技术是保护计算机系统和网络中的敏感信息和关键资源的一种重要的信息安全技术。但是传统的访问控制方法只能被动地对用户的访问请求进行响应,无法完全适应如今不断动态变化的网络环境。为了提高访问控制中系统应对恶意攻击和威胁的能力,基于博弈论中的非合作博弈方法,设计了一套适用于访问控制模型的安全机制,当访问主体提出访问请求后,对访问主体与被访问客体进行非合作博弈,得到纳什均衡,最终通过纳什均衡与门限的比较决定是否对访问主体进行授权。实验证明了该安全机制的有效性。

Abstract:

Access control technology is an important information security technology to protect the sensitive information and critical resources in computer system and network.But traditional access control methods could only respond to access requests of users passively and can’t meet the changing dynamic network environment.In order to improve the ability to respond to malicious attacks and threats in access control system,a security mechanism is designed,which is suitable for access control,based on non-cooperative game theory in the game.When the subject makes an access request to the object,there will be a non-cooperative game between them to get Nash equilibrium.Then the security mechanism will compare the probabilities in the Nash equilibrium to the setting thresholds to get the conclusion that whether to authorize the subject or not.Experiment proves the effectiveness of the security mechanisms.

Key words: access control, non-cooperative game, level-permissions-payoffs table, level-permissions-threshold table
