How to use trusted computing technology to build a multi-party secure computing system?

In modern society, protecting privacy and security has always been an important issue. The development of computer technology enables people to perform various forms of calculations on the network, thus bringing great convenience and innovation to digital life. However, the openness of computer networks and the easy leakage of information also make it necessary to adopt corresponding technical means to ensure the privacy and security of multi-party data calculations. To this end, trusted computing technology emerged as the times require. It can not only meet the current needs of big data applications, but also ensure the efficiency and effectiveness of multi-party data calculations while ensuring data privacy. This article will introduce trusted computing technology, focusing on how to use this technology to build a multi-party secure computing system.

1. The principles and applications of trusted computing technology

Trusted computing technology uses hardware security modules (TPM) to store computer privacy and security information in a secure area, and then uses Trusted software is used to keep this security information to ensure that computer-related information will not be tampered with or disclosed. The benefits of applying trusted computing technology are: first, it can improve computing efficiency while ensuring information security. Second, it allows data to be computed without leaving the local environment. This form of computing is called "protected computing." Third, it can use a variety of different encryption technologies to ensure data privacy and confidentiality, such as obfuscation technology, homomorphic encryption, and zero-knowledge proof.

Trusted computing technology has a wide range of applications, including: cloud computing, Internet of Things, blockchain, artificial intelligence, privacy protection, etc. Among them, in cloud computing scenarios, trusted computing not only improves the utilization of computer resources, but also ensures the privacy and confidentiality of cloud computing data. In the IoT scenario, trusted computing technology can ensure the privacy and confidentiality of IoT devices and terminal devices, thereby improving the security of IoT communications. In the blockchain scenario, trusted computing technology can ensure the security and credibility of blockchain data by entering custody. In artificial intelligence scenarios, trusted computing technology can use homomorphic encryption technology to allow computing nodes to perform the same computing operations, thereby avoiding the public circulation of data and privacy leakage. In privacy protection scenarios, trusted computing technology can use zero-knowledge proof technology to prove the correctness of data without revealing the data itself.

2. Ideas for building a multi-party secure computing system

In order to realize the application of trusted computing technology in multi-party data computing, we need to build a multi-party secure computing system. The design of this system should have the following characteristics:

1. Multi-party participation

The multi-party secure computing system must allow multiple participants to perform data calculations at the same time, and each referrer needs to The data is processed accordingly to ensure its security and privacy. In addition, the distributed architecture can better optimize network performance and further improve privacy and security levels.

2. Data Privacy Protection

Multi-party data calculation requires interactive calculations from multiple data sources, so sensitive data must be protected. For this purpose, methods such as encryption technology, homomorphic encryption technology, and budget algorithms can be applied to protect data.

3. Result verification

Ensuring the correctness of the results is the basis for multi-party data calculations. Most people tend to think that multi-party secure computing is the sharing of data, but in fact, after the data is shared, the calculation results must be verified during the sharing process to obtain consistent results among multiple participants. Finally, the source of the data is recognized.

In order to meet the above requirements, the basic process of building a multi-party secure computing system is as follows:

1. Install the hardware security module

Multi-party data calculation needs to ensure participation in the calculation All computer environments are trusted. Therefore, hardware security modules need to be installed to ensure the security and trustworthiness of the computer environment.

2. Data Encryption

Encrypt the data that needs to be processed to ensure privacy. Here you need to choose the appropriate encryption algorithm and key length.

3. Data segmentation and equalization

Data segmentation can split big data into small data and evenly distribute it to multiple different calculations node. This splitting and equalizing process can perform random node selection to ensure that the processing results will not be blocked or drag down the entire computing process.

4. Distributed multi-party computing

In the process of distributed computing, each node can perform calculations independently and only expose the results of the corresponding calculations. This process can optionally use multi-party computation tables, obfuscation techniques, homomorphic encryption or zero-knowledge proof techniques.

5. Calculation result verification

Multi-party calculation results can only be verified for correctness during distribution, so it is necessary to choose an appropriate algorithm to verify the consistency and integrity of the calculation results. For example, cryptographic verification and publicly verifiable schemes can be generated during the result verification process.

3. Conclusion

Trusted computing technology provides better solutions for data privacy and security. For multi-party data calculations, trusted computing technology can provide protection and privacy, ensuring the correctness and consistency of calculation results. By building a multi-party secure computing system, we can expand the application scope of data to more fields and effectively maintain the confidentiality and privacy of data. In the future, trusted computing technology will further optimize data computing, improve data privacy and security, and realize the digital era.
