With the development and popularization of Internet technology, network security has become the focus of attention. Vulnerabilities and back doors are regarded as two of the main reasons of network security problems. Dynamic heterogeneous redundant (DHR) architecture is a typical framework of cyberspace mimic defense. It can make use of untrusted hardware and software components to construct a high reliable and high security information system. In this article, a mathematical model is set up for the DHR architecture, and the system security is characterized by vulnerability consistency rate and success rate of system attack. The antiattack ability of the DHR system is analyzed using the mathematical model.

动态异构冗余系统的建模与分析

随着互联网技术的发展和普及，网络安全成为人们关注的焦点。漏洞和后门被认为是网络安全问题的两个主要原因。动态异构冗余（DHR）架构是网络空间拟态防御的典型框架。它可以利用不受信任的硬件和软件组件来构建一个高可靠和高安全性的信息系统。本文建立了DHR架构的数学模型，以漏洞一致性率和系统攻击成功率来表征系统安全性。使用数学模型分析了DHR系统的抗攻击能力。
