The development history of trusted computing technology

Trusted computing technology is a technology designed to protect computer systems from malicious attacks and unexpected behaviors. This technology is widely used in various occasions, such as military, government, finance, medical and other fields. With the development of computer technology, trusted computing technology has also continued to evolve. This article will introduce the development history of trusted computing technology.

In the early days of computer technology, trusted computing technology was not an important issue. This is because computer systems at that time were mainly used for scientific computing and data processing, and security was not a critical issue. Only a few organizations, such as governments and the military, are concerned with computer security and trustworthiness. Because the data handled by these organizations is critical to national security, a leak could have catastrophic consequences. Therefore, these organizations began to pay attention to computer security issues and take some measures to ensure the security and trustworthiness of data.

By the 1960s, the use of computers gradually expanded to commercial and government agencies, which led to more security issues. In order to solve these problems, many security devices with cryptography technology have been developed, such as encryption machines, firewalls and other equipment. The emergence of these devices can protect the security and credibility of computer systems. However, these devices still have some shortcomings, such as low reliability and high cost.

In the 1970s, with the emergence of the Internet, computer system security problems became more serious. Hackers and viruses began to emerge, malicious programs that could undermine the security and trustworthiness of computer systems. In order to solve these problems, trusted computing technology began to develop rapidly and expanded to the fields of operating systems and software. Secure Operating Systems (SOS) began to appear. These operating systems usually include some key security functions, such as access control, auditing, encryption, etc. The emergence of SOS can ensure the security and credibility of computer systems and has become the basis of Internet security.

In the 1980s, trusted computing technology entered a new stage. At this time, smart cards began to appear and were widely used in the financial and payment fields. A smart card is a card with an integrated security chip that can implement security functions such as identity verification and digital signatures. The emergence of smart cards has enhanced the security and credibility of computer systems and contributed to the rapid development of finance and payment fields.

In the 21st century, trusted computing technology has begun to incorporate new technologies such as artificial intelligence, the Internet of Things, and cloud computing. These new technologies have made the application scenarios of trusted computing technology more extensive. At the same time, trusted computing technology is becoming increasingly complex and requires more algorithms and models to support it. With the continuous development of trusted computing technology, its application scenarios will gradually expand, such as smart transportation, smart homes, wearable devices and other fields. At the same time, trusted computing technology will gradually improve security and credibility and become an important part of the digital society.

In summary, the development process of trusted computing technology can be roughly divided into three stages: the early stage, the Internet era and the modern stage. The development of this technology has been affected by the continuous advancement of computer technology and the development of the Internet, and at the same time it provides an important guarantee for the development of computer systems. As the application fields of trusted computing technology continue to expand, it will play a more important role and promote the development of digital society.
