Application of trusted computing technology in smart cities

With the continuous popularization and development of smart cities, there is an increasing demand for trusted computing technology. Trusted computing technology is a technology that protects computer hardware, firmware, operating systems and applications from malicious attacks. It can effectively improve the security and reliability of smart cities and greatly reduce risks in city operations. This article will introduce the application of trusted computing technology in the field of smart cities.

1. Intelligent Transportation

Intelligent transportation is an important part of smart cities, but its security is also likely to be threatened. For example, malicious attackers may cause traffic jams by tampering with traffic lights, or attack parking management systems to steal user information and commit fraud. Trusted computing technology can greatly improve the security of intelligent transportation systems. For example, an intelligent transportation system based on trusted computing technology can use secure multi-party computing technology to ensure that the status of traffic lights is not tampered with, thereby avoiding traffic jams. At the same time, the authenticity of parking data can also be verified by using a trusted computing mechanism and the user's private information can be prevented from being leaked.

2. Intelligent water and electricity supply system

The intelligent water and electricity supply system is an important part of the smart city, but there are also many security issues related to it. For example, attackers may tamper with data from water and electricity supply systems, threatening the water supply and power supply of smart cities. Trusted computing technology can use data encryption and data integrity verification technology to ensure the security of smart water and electricity supply systems. For example, trusted computing technology can use data encryption technology to ensure the security of data transmission, and can also use data integrity verification technology to avoid paralysis of the entire system due to data tampering.

3. Intelligent Park Management System

The intelligent park management system is a system that manages various IoT devices connected to the Internet, with the purpose of optimizing the service management of the park. This kind of system is often attacked by attackers because various devices in the campus have no protective measures and are therefore easy targets for attacks. Trusted computing technology can be used to protect smart campus equipment from malicious attacks during operation. For example, trusted computing technology can use virtual protected environment technology to protect the device's software and data to ensure device security.

With the continuous development of smart cities, people's demand for trusted computing technology is also increasing. This technology has important application value in intelligent transportation, intelligent water and electricity supply systems, and intelligent park management systems, and can greatly improve the safety and reliability of the system. However, in practice, there are still many problems with trusted computing technology, such as its security, scalability and performance, which require further in-depth research and improvement in order to better serve the development of smart cities.
