With the rapid development of artificial intelligence, in the open communication environment, interference and network attacks on intelligent terminals are more frequent. Therefore, communication security and system security issues in the intelligent platoons become hot topics. Motivated by these, the concept of zero trust was proposed. Under this communication framework, all clients are not trusted by default, and the principle of “never trust, always verify” is followed. In order to maintain communication, they need to be authenticated and authorized. This work discusses the zero‐trust framework and mechanism aiming at communication security and gives the structure and module function in detail. Moreover, the impact of malicious cyber‐attacks on the network is parameterized, and the safety coefficients of the full‐trust and zero‐trust frameworks are compared to show the effect of the zero‐trust framework on information security. After that, the research studies range from information security to system security, where the effects of the zero‐trust framework on terminal distribution, controller design, and system stability are studied, taking an intelligent connected vehicle platoon as an example. Finally, three examples verify the positive impact of the zero‐trust framework on network information security.
