How to use trusted computing technology to build a trusted transportation system?

With the acceleration of urbanization, problems such as traffic congestion, frequent accidents, and environmental pollution need to be solved urgently. In order to improve the safety, reliability and intelligence level of the transportation system, trusted computing technology has become an important means to build a trustworthy transportation system. This article will introduce trusted computing technology and its application in building trusted transportation systems.

1. Introduction to Trusted Computing Technology

Trusted computing refers to the use of hardware and software technologies with definition and verification mechanisms to ensure the confidentiality, integrity, and availability of system services and execution environments. and machine authenticity. It relies on means such as physical protection, security protocols, and embedded systems to ensure that the software and data executed by the system will not be maliciously tampered with, implanted with backdoors, or snooped.

The core technologies of trusted computing include hardware encryption, virtualization, secure boot, data protection and intelligent management. Among them, hardware encryption refers to using the security area inside the chip to implement operations such as data encryption, signature and decryption; virtualization refers to converting physical resources into multiple virtual resources, thereby improving resource utilization and flexibility; Security Startup refers to the use of secure startup technology to authenticate software and data when the system starts and ensure that the system will not be maliciously attacked during operation.

2. Application of Trusted Computing Technology in the Transportation Field

The application of trusted computing technology in the transportation field mainly includes transportation intelligence, traffic data security, and Internet of Vehicles security.

1. Traffic intelligence

Traffic intelligence refers to the use of advanced information technology, intelligent algorithms, sensors and other means to monitor and control traffic flow, status and safety in real time. Regulation. Trusted computing technology can encrypt and sign data, ensure the integrity and confidentiality of data transmission, and prevent data from being illegally stolen or tampered with. At the same time, trusted computing technology can also realize the identity authentication of vehicles and the authentication of terminal equipment, improving the safety and reliability of the transportation system.

2. Traffic data security

Traffic data includes traffic flow, vehicle information, driver information, etc. This data is extremely important to both traffic managers and vehicle owners. Trusted computing technology can protect the confidentiality and integrity of traffic data and prevent data from being tampered with or leaked. For example, trusted computing technology can be used to encrypt and authenticate data in vehicle-mounted terminal equipment, ensuring data security during data transmission.

3. Internet of Vehicles Security

The Internet of Vehicles refers to connecting vehicles to the Internet to realize information exchange between vehicles and between vehicles and road facilities. Trusted computing technology can protect the security and privacy of the Internet of Vehicles. For example, trusted computing technology can be used to authenticate software and data in vehicle terminal equipment to prevent terminal equipment from being maliciously attacked or implanted with backdoor programs.

3. Summary

Trusted computing technology plays an important role in building a trusted transportation system and can improve the safety, reliability and intelligence of the transportation system. In the future, trusted computing technology will be more widely used and play an important role in smart cities, smart transportation, logistics and other fields.
