Speaking of this Post-, which is the so-called post-quantum cryptography. Many people may not know that, so I just thought about it and talked to you. This is actually quite different from the general cryptography we usually know. Traditional cryptography relies on some complex mathematical problems to protect our information and ensure safety. However, post-quantum cryptography is mainly about dealing with the risk of quantum computer attacks that may arise in the future. Everyone has heard of quantum computers. If it has made great progress, the security of many traditional encryption will be affected. Then, Post-I want to find some new ways to keep our information safe and stable.
Let’s talk about the types of technologies it uses first and list them here for you to take a look.
1. Cryptography based on cryptography
Speaking of the cryptographic system based on grid, it is very complex and abstract. Look at the points in our space, the structure built according to certain rules is a grid. Then to develop an encryption and decryption method that is highly resistant to quantum algorithms, you must find the characteristics of this new structural algorithm to construct it. To put it more plainly, it is like finding a new building material and thinking about how to build a solid castle. You have to figure out how to build a house. Then using this mechanism to encode passwords is much stronger to resist various brute-force cracking or potential quantum attacks, and information security is guaranteed;
2. Code – based cryptography
This thing is based on error correction coding theory. For example, if we have errors when transmitting data, then this theory has ways to identify and correct these problems. Then using it to build an encryption system is the Code-based set in the field of cryptography. Think about it, Post-quantum cryptography, the problem-solving mode in information transmission, should be used in connection with encryption. This can better resist brute force cracking and ensure that information transmission is smooth;
3. Hash-based cryptography
Let’s look at the hash-based situation! Do you know the hash function? Hash processing is to turn different data into fixed-length sequences. This ensures that the original information cannot be directly output through the hash value reverse, so it is often used to do things like authentication, digital signatures and data integrity verification. In such a serious situation as quantum computers are "at the city". Post – It is important to emphasize the use of hash function to ensure information security. If you use the information authentication or signature process, rely on it and verify it, it will be more accurate and without any problems;
4. Cryptography based on coding geometry,
We also have to talk about the password based on coding geometry. This password connects algebraic geometry and coding theory, and transforms the advantages of the two disciplines like a bridge to build a special encryption method to resist the unknown harm caused by potential quantum future invasion operations. Using the unique characteristics of coding and geometry to combine them, we have developed a complex method that can block the powerful effects of quantum computers. It’s like in real life that we use several powerful defense tools to form stronger protection barriers in a comprehensive way.
When you think about the differences between these technologies, you can do this: Compared with grids and hashing, Code-based focuses on error correction mechanisms and application correlation, and uses the different functions of specific mathematical models to create a suitable application background guarantee security mechanism. The grid has the characteristics of using the spatial point set structure. Hash mainly uses regular transformation of data to sequences. Code based highlights the combination of error detection and repair methods to lay a solid theoretical foundation for cryptography operations. As for coding geometry, the "prominence" introduced a cross-combination of algebraic geometry and coding, the ideas are different. Each has its strengths and weaknesses.
For these specific issues,
Q: How do I choose a technology for post-quantum cryptography to use for digital signatures?
Answer: For example, hashing technology, the digital signature process mainly requires rapid authentication and non-forgery. Because some advantages of hashing technology, such as the data mapping characteristics mentioned above and the uniqueness of its mathematical characteristics, are very consistent with the required characteristics in actual scenarios when used in combination. If a digital signature scheme based on grid or coding geometry is applied, the technology is much more complex, but if the scenario requires strict key distribution guarantees, its mechanism may be able to adapt well to the environment needs to fill the situation where hash cannot cope with it, we have to measure and choose.
Q: What kind of cryptographic technology application should be focused on to ensure the security of the underlying communication of cloud services?
Answer: If you consider the underlying cloud, you should consider resisting external potential quantum and various known software and computing utilization capabilities. Those with stronger synthesis should be given priority. Hash digital technology has advantages at the basic algorithm level, but if the coding-based related mechanism can be highly integrated with the existing foundation, the extended performance can provide better basic guarantees for this kind of environmental communications, it can also play a role if it can combine new security architectures and cloud computing architectures to achieve new developments.
The post-quantum era is coming, as if the wind is approaching. We must think of some tricks to deal with "future wind and disasters" to protect our homes. We must plan early. When choosing different encryption technologies for integration, you must consider them in combination with actual conditions in order to truly make good use of them. Provide global procurement services for weak current intelligent products! After all, it is true that it is true that it is true that it is true, and it is the final result that we all hope to see. Finally, multiple technologies should be developed in parallel or cross-disciplinary to seek integration points. Comprehensive development is the most suitable countermeasure against the "new generation of destructive factors". The post-quantum safety net is tied tightly and protected!
