How to build a trusted email system using trusted computing technology?

With the widespread use of email, security and credibility have become one of the important issues that users need to protect. Traditional email systems rely primarily on encryption and authentication technologies to protect their security, but these methods do not always provide adequate protection. Trusted Computing technology provides the possibility to solve this problem. This article will introduce how to use trusted computing technology to build a trusted email system.

1. Trusted Computing Technology

Trusted Computing Technology is a security mechanism that utilizes the cooperation of hardware and software to protect computer systems from malware and malicious software. attack. The basic principle is to verify the integrity and security of the system by using a Trusted Platform Module (TPM) chip and ensure that the system only runs verified software.

2. Basic steps to build a trusted email system

Building a trusted email system based on trusted computing technology requires the following basic steps.

2.1 Add a TPM chip

First you need to add a TPM chip to the computer system. The TPM chip is usually located on the computer motherboard and can provide hardware-level security authentication and encryption functions.

2.2 Prepare a trusted environment

When building a trusted email system, you need to build a trusted operating environment. This environment should be proven, safe and secure. Preparing for a trusted environment includes the following steps:

• Use a secure operating system. Such as Windows' BitLocker or Mac's FileVault, etc.
• Install all necessary security patches and updates.
• Configure firewalls and restrict communication channels for email clients.
• Configure the necessary security settings for the email service and client. For example, disable external links, increase password strength and encryption level, etc.

2.3 Enabling the TPM chip

Enabling the TPM chip is one of the important steps to verify the computer system. To enable the TPM chip, you need to follow the following steps:

• Check whether the computer motherboard supports the TPM chip and enable its BIOS settings.
• Install TPM driver and software.
• Activate the TPM chip to start using it. Common methods include enabling BitLocker, SafeGuard, etc.

2.4 Perform email authentication

Using trusted computing technology, an email authentication system based on two-factor authentication can be built. This can be achieved through the following steps:

• Create a TPM security key (Secure Key).
• Store the key in the TPM chip.
• When users log in to their email, they need to use the security key of the TPM chip for authentication. At this time, you need to enter the correct email password and the BIOS password of the computer system or other two-factor authentication authentication method.
• After being authenticated in this way, all messages in the email system can be considered to be from a trusted user and can be transmitted and stored securely.

3. Strengthen email security with trusted computing technology

In addition to the basic steps, you can further strengthen email with trusted computing technology in the following ways System security:

3.1 TPM chip hardware verification

Using the hardware verification function of the TPM chip can further improve the real-time security performance of the system. This function can monitor the system startup and running status, and can provide timely alerts and prevent malicious attacks.

3.2 Remote access management

Using the remote access management function of the TPM chip, remote management and security monitoring of the computer system can be achieved. Therefore, even if the computer is attacked or lost, administrators and data owners can control and protect it through remote access.

3.3 Digital signature and encryption

Using trusted computing technology, emails can be digitally signed and encrypted. Digital signatures can ensure the authenticity and integrity of emails, while encryption can protect the privacy and confidentiality of emails, further improving the security of the email system.

4. Conclusion

Using trusted computing technology to build a trusted email system can improve system security and reliability while protecting the privacy and integrity of data. By adding a TPM chip, building a trusted environment, enabling the TPM chip, performing authentication and other basic steps, we can implement security features such as two-factor authentication, encryption and digital signatures in the email system. In addition, the security of the system can be further improved through other trusted computing technologies. In the future, trusted computing technology will become the core guarantee for email system security.
