Uncertain security threats caused by vulnerabilities and backdoors are the most serious and difficult problem in cyberspace. This paper analyzes the philosophical and technical causes of the existence of so-called “dark functions” such as system vulnerabilities and backdoors, and points out that endogenous security problems cannot be completely eliminated at the theoretical and engineering levels; rather, it is necessary to develop or utilize the endogenous security functions of the system architecture itself. In addition, this paper gives a definition for and lists the main technical characteristics of endogenous safety and security in cyberspace, introduces endogenous safety and security mechanisms and characteristics based on dynamic heterogeneous redundancy (DHR) architecture, and describes the theoretical implications of a coding channel based on DHR.

由漏洞和后门引起的不确定性安全威胁是网络空间中最严重、最棘手的问题。分析了系统漏洞、后门等所谓“暗功能”存在的哲学和技术原因，指出内生安全问题在理论和工程层面无法完全消除；相反，有必要开发或利用系统架构本身的内生安全功能。此外，本文对网络空间内生安全保障的主要技术特点进行了定义和列举，介绍了基于动态异构冗余（DHR）架构的内生安全保障机制和特点，
