The era of "AI" has come, and the issue of data security has come to the fore. The enemy of network security is no longer the problem of the information system itself, but the deadly operational risk. Data encryption technology is also courageously moving forward in this torrent, constantly improving, and escorting all the way in this era of the Internet of everything!

Data encryption is a very ancient technology, as early as more than 2000 BC, the Egyptians began to use special hieroglyphs as information coding to protect their secret documents; and the Phaistos disk invented by Crete in the 17th century BC is regarded as one of the most difficult codes to crack. Because of the openness of the Internet, it is difficult to achieve all aspects of information security. So how to protect the security of these data has become a problem that every enterprise has to ponder and consider!

The development of data encryption technology can be roughly divided into three stages.

Before 1949, the early data encryption technology was simple, the complexity was not high, and the security was low. Most of them were crossword puzzles with artistic characteristics. Therefore, the password of this period is called classical password. With the advent of the Industrial Revolution and the outbreak of World War II, data encryption technology has made a breakthrough. Plaintext can be transformed into ciphertext by cryptographic algorithm or mechanical encryption equipment.

From 1949 to 1975, from the birth of the world's first computer to today, computer technology has developed by leaps and bounds, which has promoted the encryption technology from the mechanical age to the electronic age. This not only makes the encryption technology of complex computing possible, but also makes the encryption algorithm greatly improved in complexity and security.

From 1976 to now, American cryptography experts Di Bang and Herman put forward the concept of public key cryptosystem in 1976, which is a great invention of modern cryptography and provides a new direction of cryptography. The process of data encryption is to change the plaintext into ciphertext through the encryption system. Data encryption technology is mainly divided into data transmission encryption and data storage encryption. Data transmission encryption technology mainly encrypts the data stream in the process of data transmission, such as link encryption, node addition and end-to-end encryption. There are many kinds of storage encryption algorithms. At present, the most commonly used algorithms are DES algorithm, RSA algorithm, PGP algorithm and so on.

With the frequent occurrence of information security accidents, people pay more and more attention to technological innovation and innovation in the field of data security. The rapid development of science and technology not only brings a lot of convenience to people, but also makes the means of * * emerge in endlessly. It is reported that the Finnish 10-year-old boy, who does not have his own Ins account, can delete user comments on all posts. He is the youngest person to hack into Ins. It is hard to imagine that a child of such an age should have reached such a level. Looking back on my 10-year-old, I am ashamed of myself. The above phenomenon gives us a warning. Nowadays, * * is becoming more and more instrumental. It can be said that a person who knows nothing about computers may bring inestimable losses to an enterprise by clicking on a button of a tool. A stricter focus is more likely to bring safety to everyone. This is not alarmist talk. Data security is not only an internal problem of a company, but also a major issue of social stability and national prosperity.

Traditional encryption technology is also the infrastructure of the network construction of enterprises and institutions, such as firewall, * detection, anti-virus, of course, these are far less than the current technological innovation. New encryption technology also arises at the historic moment, such as host monitoring, document transparent encryption and decryption technology, SDC sandboxie concept and so on. Document encryption uses the application layer transparent encryption technology, commonly known as hook transparent encryption technology. This technology originated in the win98 era and became popular with windows2000. Is the combination of the above two technologies (application layer API and Hook). The hook technology of windows is used to monitor the application's opening and saving of the file. when opening the file, the ciphertext is converted first and then the program is read into memory to ensure that the program reads plaintext, and when saving, the plaintext in memory is encrypted and then written to disk. Application layer APIHOOK encryption technology is characterized by simple implementation, poor reliability and slow speed, because it needs temporary files and is easy to crack. And for some large drawing files, it is also easy to cause damage, not to mention the impact on developers, not to mention the progress of the project. However, due to the direct encryption of files intuitive feeling is very good, for the original blank market, this banner really moved many enterprises. And the concept of SDC sandboxie is developed on the basis of the former, each filter layer only does what they are good at, so it is particularly stable, fast, reliable performance, without any problems.

Data encryption technology is a necessary supplement to enterprise prosperity, social stability and national security!
