Application of trusted computing technology in the field of Internet of Vehicles

With the development of information technology and the advancement of vehicle intelligence, the Internet of Vehicles has become one of the hot spots of concern. However, with the popularity of the Internet of Vehicles, the security issues involved have become increasingly prominent. Therefore, how to ensure the information security and reliability of the Internet of Vehicles system has become an urgent problem. As a safe and reliable technical means, trusted computing technology has begun to be applied in the field of Internet of Vehicles. This article discusses the application of trusted computing technology in the field of Internet of Vehicles.

1. Basic principles of trusted computing technology

Trusted computing technology is a technology that provides computer system security and reliability, which can be derived from system hardware, operating system and applications, etc. Angle ensures the information security and reliability of computer systems. The basic principle is to isolate the trusted computing environment of the system to ensure that the computing tasks performed in this environment are safe and trustworthy. The main feature of trusted computing technology is that it has three functional modules: protection, detection and repair. The protection module is used to ensure the credibility of the system, the detection module is used to monitor attack behaviors in the system, and the repair module is used to repair the system. vulnerabilities and risks.

2. Application of trusted computing technology in the field of Internet of Vehicles

(1) Application of trust chain technology

Trust chain technology is an application of trusted computing technology , which ensures trusted transmission of data throughout the system. In Internet of Vehicles applications, chain of trust technology can be used to authenticate communications between vehicles and transportation infrastructure. For example, in a car's autonomous driving system, a hardware security module is used to store the private key, and the information between it and the vehicle is encrypted and verified through trust chain technology to ensure safe driving of the car.

(2) Application of secure startup technology

Trusted computing technology can also be used for safe startup of vehicle systems. In systems protected by a trusted computing environment, secure boot technology ensures a safe system startup process. In the field of vehicles, because the electronic control system of a car is more complex than an ordinary computer system, trusted computing technology can play an important role in ensuring the safety and reliability of the startup process.

(3) Application of data security transmission technology

The data transmission involved in the Internet of Vehicles applications is generally transmitted through wireless signals, so data transmission security has become an issue that must be paid attention to in the Internet of Vehicles. . Trusted computing technology can ensure the security and reliability of data transmission by encrypting and decrypting data. For example, trusted computing technology is used on the Internet of Vehicles gateway to encrypt and decrypt data to ensure safe data transmission.

3. Advantages of trusted computing technology in the Internet of Vehicles

(1) Improving information security

In the application of the Internet of Vehicles, ensuring information security is the most basic requirements. Trusted computing technology can ensure information security by protecting the computing environment and verifying data transmission, thereby effectively preventing malicious attacks and data leaks.

(2) Improve system reliability

Trusted computing technology can improve the reliability of the Internet of Vehicles system and ensure security and stability during data transmission. In the Internet of Vehicles system, trusted computing technology can improve the reliability and stability of the system and ensure efficient operation of the system by protecting the computing environment, monitoring attacks in the system, and repairing vulnerabilities in the system.

(3) Improve system scalability

Trusted computing technology can help Internet of Vehicles applications achieve better scalability. By establishing a scalable trust chain system and a secure startup system, trusted computing technology can help Internet of Vehicles applications more effectively achieve system scalability and improve system availability.

Generally speaking, the application of trusted computing technology in the field of Internet of Vehicles helps to improve the information security, reliability and scalability of the Internet of Vehicles system and realize the existence and transmission process of systems and data. security and confidentiality. Due to the rapid development of Internet of Vehicles applications, the application of trusted computing technology will become more extensive and in-depth. The technology and application of trusted computing technology will have a broader application space in ensuring the data security and reliability of Internet of Vehicles applications.
