The objective of the current research is to draw attention to the impact of international characteristics of e-commerce on the sovereignty of state, and to identify the factors affecting this sovereignty. The issue of the dynamieity of time and place will be taken into consideration, where activities carded out over the internet are characterized by their cross-border dimension. Based on real e-commerce case studies disputed on international level, this paper will draw on the legal perspective of cyberspace, identifying the relationship between cyberspace and state sovereignty, and outlining the mechanisms by which cyberspace could cross borders and the territory of the state despite all the precautions taken by the state to protect its sovereignty.展开更多

Traditional static passive defense technologies focus on external security and known threats to the target system and cannot resist advanced persistent threats. To solve the situation that cyberspace security is easy to attack and difficult to defend, Chinese experts on cyberspace security proposed an innovative theory called mimic defense, it is an active defense technology that employs “Dynamic, Heterogeneous, Redundant” architecture to defense attacks. This article first briefly describes the classic network defense technology and Moving Target Defense (MTD). Next, it mainly explains in detail the principles of the mimic defense based on the DHR architecture and analyzes the attack surface of DHR architecture. This article also includes applications of mimic defense technology, such as mimic routers, and mimic web defense systems. Finally, it briefly summarizes the existing research on mimic defense, expounds the problems that need to be solved in mimic defense, and looks forward to the future development of mimic defense.展开更多
