How to use trusted computing technology to build a trustworthy smart city system?

With the continuous acceleration of urbanization, smart cities have gradually become the mainstream trend of urban development. Smart city systems are based on big data, cloud computing, Internet of Things, artificial intelligence and other technologies to achieve intelligent management and services in urban transportation, security, environment, energy and other aspects. However, as urban systems become more and more intelligent, the security issues of urban systems are becoming more and more prominent. How to ensure the safety and reliability of smart city systems has become a major challenge in smart city construction.

Trusted computing technology is a technology that protects the security and credibility of computer systems. It ensures the integrity, credibility and confidentiality of the execution environment of the computer system through hardware, software and protocols. Trusted computing technology plays an important role in the security of smart city systems. How to use trusted computing technology to build a trustworthy smart city system? This article will discuss the definition, application scenarios, and technical solutions of trusted computing technology.

1. The definition and principle of trusted computing technology

Trusted computing means that the computer system protects the integrity and credibility of the execution environment of the system without being maliciously attacked. and confidentiality. Trusted computing technology can ensure system security through various means such as hardware, software and protocols. The most important of these is the Trusted Platform Module (TPM). TPM is a hardware security module with a chip specially designed for security purposes, which can provide a variety of security measures such as security encryption, identity authentication, and digital signatures. The basic principle of TPM work is to divide the computer system into two parts: a protected secure execution environment (Trusted Execution Environment, TEE) and an unprotected local execution environment (Local Execution Environment, LEE). TPM verifies the credibility of the system through TEE to ensure that only trusted software can run on the system.

2. Application scenarios of trusted computing technology in smart cities

1. Urban traffic safety

Urban traffic safety is one of the important issues in the construction of smart cities. A safe and reliable traffic signal control system can be built using trusted computing technology. The traffic signal control system can detect and control urban traffic conditions in real time by integrating sensors, cameras, signal controllers, processors and other equipment. Trusted computing technology can ensure the integrity and credibility of the traffic signal control system and prevent security issues such as hacker attacks and data tampering.

2. Urban security monitoring

Urban security monitoring is an important aspect of smart city security. Trusted computing technology can build a safe and reliable urban monitoring system and improve the credibility and integrity of monitoring data. This data can include video surveillance, police dispatch, security resource management and other information. Trusted computing technology can ensure the integrity and credibility of these data and prevent security issues such as hacker attacks and data tampering.

3. Urban environment monitoring

Urban environment monitoring is an important aspect in the construction of smart cities. Trusted computing technology can build a safe and reliable environmental monitoring system and improve the credibility and integrity of environmental monitoring data. These data can include air pollution, water quality monitoring, noise monitoring and other information. Trusted computing technology can ensure the integrity and credibility of these data and prevent security issues such as hacker attacks and data tampering.

3. Technical solution of trusted computing technology

The technical solution of trusted computing technology includes the following three aspects:

1. Trusted Platform Module (TPM)

The trusted platform module is a core component of trusted computing technology and can protect the integrity, credibility and confidentiality of the execution environment of the computer system. The basic principle of how TPM works is to divide the computer system into two parts: a protected secure execution environment (TEE) and an unprotected local execution environment (LEE). TPM verifies the credibility of the system through TEE to ensure that only trusted software can run on the system.

2. Trusted startup

Trusted startup means ensuring that every component of the computer is trustworthy when the computer starts the system. Trusted boot can prevent security threats such as malware and hacker attacks and protect the credibility of computer systems.

3. Trusted identity authentication

Trusted identity authentication refers to ensuring that computer systems and other devices or services are trusted through standardized identity authentication protocols and methods. Trusted identity authentication can prevent security issues such as unauthorized access and data leakage, ensuring the security and reliability of smart city systems.

To sum up, trusted computing technology has important application value in the construction of smart cities. Trusted computing technology can ensure the security and reliability of smart city systems through various means such as hardware, software, and protocols. Applying trusted computing technology to build a trusted smart city system can realize intelligent management and services in urban transportation, security, environment, etc., and improve the efficiency and quality of urban operations.
