Building Internet information security with blockchain technology

Currently, although Internet information security technology continues to develop, the overall Internet security situation is still very severe. Blockchain technology adopts a distributed and trustless center architecture, based on mathematical encryption algorithms, by generating interrelated data blocks with time stamps and information verification, forming traceable, verifiable, non-tamperable, and non-forgery Data can fundamentally guarantee the integrity and security of information data. In view of this, this article discusses a new paradigm of Internet information security based on blockchain technology, hoping to effectively make up for the shortcomings of traditional Internet defense strategies and improve the Internet information security system.

Building Internet information security with blockchain technology

1 The Internet security situation remains grim
The development of Internet technology has provided great convenience for our lives and work. However, due to the high degree of openness of the Internet, information leakage problems have occurred frequently, and the Internet security situation is very severe. When people use the Internet, they will inevitably involve relevant industry information or other information data, and these information data are usually not processed by security encryption. In this case, many criminals will use such a loophole to use some Internet facilities to intercept the electronic information in the transmission process, and then use a series of technical means to obtain the e-commerce information. The data undergoes secondary processing and processing. In this way, the information after secondary processing and processing not only loses its authenticity and validity, but after it is released, it is easy to cause serious misleading to others, and cause some property theft and information security problems.

Although network technology can bring many conveniences to modern social life, at the same time, due to its own open characteristics, it is also easy to cause security problems. It has always been a key issue of widespread concern. Because some netizens or some network attackers can invade e-commerce computers at will, it will pose a serious threat to the information and property security of network users. After invading the computer network, you can master some confidential documents in e-commerce, and then you can make arbitrary changes to these documents according to your own needs, which will not only cause the information to lose its authenticity and validity, but also cause serious consequence.

2 The necessity of building a security fortress for Internet information systems
In the Internet era, computers are widely used in people's work and life due to their large capacity, fast and convenient advantages. Various industries in the society have introduced modern office equipment to achieve intelligent integration. With the innovation and development of the Internet, the network has quietly changed the pace of people's lives and work with high-efficiency transmission and real-time interactivity. All walks of life use computers to process work, use the Internet to communicate, and understand the outside world. More and more applications are developed to meet people's individual needs, such as email, online shopping, information processing, stock trading, etc. It is a network application based on a computer foundation. The characteristics of the Internet are interconnection, openness, and anonymity. It is precisely because of this characteristic that information is insecure. Information loss, theft, and forgery are extremely common. This makes the Internet have certain security risks and problems. The solution will seriously affect people's trust in the network, and make people afraid of the network and afraid to approach it. Only by fully understanding and mastering computer security technology and protection methods can computer security be effectively ensured and reliable network interconnection can be achieved.

With the development of science and technology, computers have gradually entered thousands of households. They are not only entertainment and simple tasks, but also very important tools in people’s lives and work. More and more information is stored. The more important it is. Therefore, once the security barrier of the computer system is breached, the loss is immeasurable. Therefore, it is imperative to build a fortress of Internet information security.

3 Internet security applications based on blockchain technology
Blockchain technology has a very wide range of application prospects, especially in terms of network information security and protection

3.1 Anti-data tampering of VPC
The inability to tamper with is a very important feature of the blockchain. Even if the information of the blockchain can be viewed, the verification, sending, and communication of the blockchain information are based on hashing and hashing algorithms. This structure and algorithm make it almost impossible for information counterfeiters to change the information data in the blockchain in a single aspect. Therefore, the application of blockchain technology can not only ensure the correctness of information and data sources, but also prevent data from being intercepted during transmission. This feature has a very good effect on reducing Internet information security risks.

3.2 Protect basic Internet services and prevent distributed denial of service attacks
Traditional Internet protection technologies need to rely on DNS servers for protection in the face of attacks, and the number of DNS servers is limited. Therefore, when the supply exceeds the upper limit of these DNS servers, they cannot provide protection services for the Internet. The application of blockchain technology enables the Internet system to directly use each node in the blockchain network to realize the function of DNS service when facing an attack. Therefore, in fact, the network has a very large number of nodes running the blockchain DNS service system at all times, so users can always access domain names on the Internet, and no one can control and prevent such access. In this situation, if an attacker wants to successfully launch an attack, the resources needed to call are very large, which is almost impossible to achieve. At the same time, this is more harmful than good for the attacker.

Internet security issues involve many aspects. This not only requires Internet users to develop good habits and awareness of prevention in the long-term use process, but also actively use new technologies to build an Internet information security bastion. The development of blockchain technology provides a new paradigm for Internet information security that is completely different from traditional forms of security protection. Using blockchain technology to protect Internet security can perfectly protect user basic information, transaction information, communication information, and Internet infrastructure. However, it should be noted that any technology is a double-edged sword. It has a bright side and a dark side. There are opportunities, but it will be full of challenges. The development of new technologies will inevitably face risks, as does the blockchain. Therefore, in the application process of blockchain technology, we must comprehensively consider, maximize the advantages of blockchain technology, and build an excellent new paradigm of Internet information security.
