Application of trusted computing technology in the field of data sharing

With the acceleration of data generation and flow, data sharing has become an increasingly important issue in the information field. In the process of data sharing, data security and privacy have always been one of the issues that people are concerned about. The emergence of trusted computing technology provides a new solution to ensure data security and privacy. This article will introduce the application of trusted computing technology in the field of data sharing from the aspects of trusted computing technology principles, data sharing scenarios, and technical applications.

1. Principle of Trusted Computing Technology

Trusted Computing is a secure computing technology based on chip technology. It builds "trusted computing" by using special chips. "Trusted Platform" ensures the integrity, confidentiality and availability of data during the computing process. It includes the following three basic parts:

1. TPM chip

TPM (Trusted Platform Module) chip is also called a security chip, which is the core implementation of trusted computing . It can ensure the trustworthiness of the computer hardware environment, that is, ensure that it is not infringed by software and malware, thereby ultimately achieving system security. TPM chips can provide authentication, data encryption, key management and trusted boot functions.

2. SGX Technology

SGX (Software Guard Extension) technology is a security encryption technology launched by Intel on the sixth to eighth generation processors. Isolated security zones can be established at the CPU hardware level. This area is known as the "hidden domain" (Enclave), in which protected applications can run without being affected by other parts of the system and external attacks.

3. Remote verification

Trusted computing technology also needs remote verification to ensure the security of the trusted system. The purpose of remote verification is to make the entire computing process of the computer system public, monitor the entire process, and use digital signature and encryption technology to ensure data privacy and confidentiality.

2. Data Sharing Scenario

Data sharing is a way of using data, mainly used for information exchange between different departments, institutions and organizations. The objects of data sharing can be individuals, organizations or other types of entities, which require certain security mechanisms to ensure the security and privacy of shared data.

1. Financial field

The financial field is one of the important areas for data sharing. Different financial institutions need to have customer information, fund transfer records and other data at the same time, but once this data is leaked, it will cause huge losses. Trusted computing technology can ensure the security of data sharing without exposing the data.

2. Medical field

The medical field is one of the important fields of data sharing. The security and privacy protection of medical data are related to the health and life safety of patients. Trusted computing technology can use encryption algorithms and secure communication protocols to ensure the safe transmission and storage of medical data.

3. Government Agencies

Government agencies are also an important area of ​​data sharing. Government agencies include data sharing between various departments of the country and between different levels. Trusted computing technology can ensure the security and controllability of data sharing between government agencies.

3. Technology Application

In the process of data sharing, trusted computing technology can provide reliable guarantee for the safe transmission and processing of data. The following will introduce the application of trusted computing technology in the field of data sharing:

1. Data encryption

Data encryption is one of the most basic methods to ensure data security. Trusted computing technology can use encryption algorithms and key management mechanisms to securely encrypt data to ensure that data is not stolen or tampered with during transmission.

2. Blockchain Technology

Blockchain technology is a distributed data storage and transaction consensus mechanism. It can utilize the characteristics of decentralization to achieve data sharing. Trusted computing technology can provide a more secure infrastructure for blockchain technology and ensure the credibility of data transmission and storage in distributed networks.

3. Data processing

Trusted computing technology can provide an isolated security environment to ensure that some data cannot be illegally accessed and tampered with. By using this technology, some data security computing scenarios can be constructed, such as authentication, data solidification, etc.

4. The future of trusted computing technology

As data sharing continues to increase and the complexity of data processing increases, trusted computing technology will play an increasingly important role in the field of data sharing. character of. In the future, trusted computing technology will continue to optimize and enhance the scalability and programmability of the technology through the application of various scenarios to better meet the data sharing needs of different industries and fields.

Conclusion:

In the scenario of data sharing, trusted computing technology can provide reliable guarantee for the safe transmission and processing of data. This technology can be used to ensure data security and privacy in different industries and scenarios. Trusted computing technology will continue to develop and innovate in the future to further improve the security and controllability of trusted computing systems.
