Cyberspace Endogenous Safety and Security Article

Jiangxing Wu

Engineering 2022, Volume 15, Issue 8,   Pages 179-185 doi: 10.1016/j.eng.2021.05.015

Abstract:

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 security mechanisms and characteristics based on dynamic heterogeneous redundancy (DHR) architecture, and describes the theoretical implications of a coding channel based on DHR.

Keywords： Uncertain threat     Cyberspace endogenous safety and security     Relative right axiom     Dynamic heterogeneous redundant

Abstract:

An assembly design system is an important part of computer-aided design systems, which are importanttools for realizing product concept design.The traditional assembly design system does not record the connection information of production on theengineering layer; consequently, the upstream design idea cannot be fully used in the downstream designAn assembly design model based on the relationship of engineering connection is presented.
