摘要： 通信安全控制能够实现网络信息的安全传输。为了满足不同层次的通信安全需要，必须提供不同的安全控制服务，建立完善的安全控制体系，运用集中与分层相结合的安全控制方式，并对通信协议进行安全扩展。除此之外，安全控制效果的检测与反馈也是保证控制系统稳定的重要环节。为此，从系统控制的角度，提出了网络通信的安全控制需求、控制体系、控制方式和异常行为检测分析模型，为具体实施通信安全控制奠定了理论基础。

Abstract: Secure communication control can achieve secure network information transmission. In order to meet different security requirements on different network layers, it is necessary to provide different security control services, to establish comprehensive controlling architecture, and to extend present communication protocols using the control style combining the characteristics of centralizing and layering. Moreover, detecting and feeding back controlling efficiency are also the important measurement for protecting system stability. In the view of system controllability, this paper proposes the control requirements, architecture, styles and abnormal behavior detection model of secure info-net communication, which forms the academic basis for implementation.
