What are the key technologies and algorithms of trusted computing technology?

With the development of the Internet, various types of computers and network equipment have become increasingly popular, and people have higher and higher requirements for data security. Threats such as fraud attacks, privacy leaks, and network viruses continue to emerge, placing high demands on the security and credibility of computer systems. Trusted computing technology emerged as the times require. It is a method that combines hardware and software to protect and ensure the security and reliability of computer systems. So, what are the key technologies and algorithms of trusted computing technology?

1. Trusted Platform Module (TPM technology)

The Trusted Platform Module (TPM for short) is one of the core technologies of trusted computing. It is a hardware chip that is installed on the computer's motherboard and is difficult to modify and attack. Used to store security-related information, such as keys and digital certificates, to ensure system authentication, encryption, and authorization.

The main function of TPM technology is to provide functions such as system random number generation, boot password negotiation, authorization encryption and plug-in mechanism. Through these functions, TPM technology can provide security protection for the entire computer system to prevent unauthorized access and data leakage.

2. Two-way authentication (SSL/TLS technology)

Two-way authentication means that the client and the server verify each other's identities to ensure that the identities of the communicating parties are true. The implementation of two-way authentication requires the help of SSL/TLS technology, which is an important secure transmission protocol in trusted computing technology.

SSL/TLS technology realizes message encryption and integrity verification by using public key encryption and digital signature technology. It can encrypt and protect data during data transmission to ensure data security. At the same time, SSL/TLS technology can also prevent man-in-the-middle attacks and tampering, ensuring the authenticity and reliability of messages.

3. Encryption algorithm (AES/SM4 algorithm)

Encryption algorithm is an important part of trusted computing technology and the core implementation to ensure data security. Currently, AES and SM4 are two widely used encryption algorithms.

The AES algorithm is a symmetric cryptosystem that uses the same key for encryption and decryption. Therefore, it is fast and efficient and is one of the most widely used encryption algorithms currently. The SM4 algorithm is a high-security symmetric cryptographic algorithm with excellent performance, high speed and high efficiency. It is one of the cryptographic algorithms recommended by the State Cryptozoology Bureau.

4. Virtualization technology

Virtualization technology is an important technology in trusted computing technology. It can convert physical resources into virtual resources and flexibly allocate and allocate virtual resources. manage. Through virtualization technology, users can create multiple virtual machines to implement different application scenarios, and isolate, collaborate and manage them.

Virtualization technology can achieve isolation and protection at the hardware level, reduce the sharing and pollution of physical resources, and increase resource usage efficiency and reliability. At the same time, virtualization technology can also provide multi-level protection for virtual machines to ensure the security environment and data security of virtual machines.

To sum up, the key technologies and algorithms of trusted computing technology include trusted platform module (TPM technology), two-way authentication (SSL/TLS technology), encryption algorithm (AES/SM4 algorithm) and virtualization technology. These technologies and algorithms play a full role in practical applications to ensure the security and reliability of computer systems and improve the overall performance and efficiency of computer systems.
