A survey for Communication security of the embedded system

Abstract

Abstract The embedded operating system is a task-oriented computing platform that can be tailored, low-cost, and has high requirements for reliability and real-time performance. It plays an extremely important role in engineering applications. With the gradual application of embedded systems in various fields, the shortcomings of its insufficient ability to respond to security threats have gradually emerged, and many hackers have turned their attack targets into embedded systems. The important reason for these attacks is that embedded systems lack sufficient multi-layer protection mechanisms. This article focuses on the threats embedded systems face in terms of communication security. Then analyze the existing communication security-related technologies from the perspectives of the network layer, the transport layer, and the application layer. Finally, it summarizes the research direction of embedded system security countermeasures.
