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

In the context of today's increasing popularity of social networks, problems such as data leakage and privacy invasion are becoming more and more serious, and trusted computing technology has become a powerful weapon to solve these problems. This article will introduce how to use trusted computing technology to build a trusted social system from aspects such as what is trusted computing technology, the core requirements of trusted social systems, and the application of trusted computing technology in trusted social systems.

1. What is trusted computing technology

Trusted computing technology is a technology that ensures the trustworthiness of computing processes and results through hardware, software, protocols and other means. It mainly includes technologies such as Trusted Platform Module (TPM), Secure Multi-party Computation (SMC), and Fully Homomorphic Encryption (FHE). They can be used for tamper-proofing, confidential computing, and privacy protection respectively. They are currently the most mature guaranteed computing. Technology with trustworthy processes and results.

2. Core requirements of a trusted social system

The core requirements of a trusted social system mainly include three aspects: data protection, identity authentication and authority control.

1. Data Protection

Data leakage and data tampering are the main hidden dangers faced by current social networks. Therefore, ensuring the confidentiality, integrity and availability of data has become the design of social systems. focus. Trusted computing technology ensures the integrity and reliability of system applications and protects the privacy and security of user data by applying hardware security modules, such as TPM.

2. Identity Authentication

The identity authentication of users in social networks is mainly achieved through user accounts and passwords, but this method is easily cracked by hackers, resulting in failed identity authentication. reliable. Trusted computing technology can be applied in the field of identity authentication to ensure that users’ identity information on the network is protected and verified through technologies such as Secure Multi-Party Computation (SMC).

3. Permission Control

In social networks, users can publish different types of information according to their own needs, so different permission controls need to be carried out according to different user roles and needs. Trusted computing technology can be used in the field of permission control to achieve access control and encryption protection of user information through technologies such as fully homomorphic encryption (FHE).

3. The application of trusted computing technology in trusted social systems

The application of trusted computing technology in trusted social systems is mainly divided into three categories: data protection, identity authentication, and authority control. aspects.

1. Data Protection

Trusted computing technology is mainly used in the field of data transmission and storage. Technologies such as encryption or hash algorithms can be used to protect the privacy and integrity of data. . For example, secure transmission protocols such as TLS/SSL are used during data transmission to ensure that data will not be stolen or tampered with during transmission. In terms of data storage, the trusted platform module is applied to add a data storage module, which can ensure the integrity and confidentiality of data storage and prevent data loss and leakage.

2. Identity Authentication

Trusted computing technology is applied in the field of identity authentication, mainly through secure multi-party computation (SMC) and other technologies to ensure that users’ identity information on the network is obtained Protect and verify. For example, multi-factor authentication is adopted in the user authentication process. In addition to verifying username and password, hardware security modules and biometric technology are also used for authentication, effectively avoiding hacker attacks and identity impersonation.

3. Permission Control

Trusted computing technology is applied in the field of permission control, and can achieve access control and control of user information through fully homomorphic encryption (FHE) and other technologies. Encrypted protection. For example, in the process of user information access control, fully homomorphic encryption technology is used to control user access to ensure the privacy, security and integrity of user information.

4. Application Prospects of Trusted Social Systems

The application of trusted computing technology can solve the unavoidable security risks faced by social networks such as data leakage and identity impersonation. This technology and social networks The combination will provide users with a more secure and reliable social environment. In the future, trusted computing technology will play a more important role in the field of social network security, promoting the healthy development of social networks and user trust.

To sum up, the application of trusted computing technology in trusted social systems will not only protect the security of user data, but also ensure the trustworthiness of user identities and the legitimacy of access. Although there are still many technical challenges in fully applying trusted computing technology in social systems, we believe that this technology has extremely broad application prospects, which will also bring a safer and more reliable environment for human social interaction.
