The era of data security solutions

“AI” Time has come , Data security issues , There are troops under the city . The enemy of network security , It is no longer the problem of the information system itself , It's a deadly operational risk problem ！ Data encryption technology is also moving forward bravely in this torrent , Continuously improve , In this era of interconnection of all things, we will escort all the way ！

Data encryption technology is a very old technology , As early as BC 2000 Many years ago , Egyptians began to use special hieroglyphs as information codes to protect their secret documents ; It began in BC 17 Invented by the Cretan people in the th century Phaistos Disk is also known as one of the most difficult passwords to crack . And the Internet because of its openness , Information security is also difficult to achieve everything . So how to protect the security of these data , Has become every enterprise has to ponder , The question to consider ！

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

1949 Years ago , Early data encryption techniques were simple , Low complexity , Low security , Most of them are 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 . Through cryptographic algorithms or mechanical encryption devices , Convert plaintext into ciphertext .

1949-1975 During the year , The birth of the world's first computer until today , Computer technology is developing by leaps and bounds , It also promotes the encryption technology from the mechanical age to the electronic age . This makes the encryption technology of complex computing possible , It also greatly improves the complexity and security of the encryption algorithm .

1976 so far , American cryptography experts deban and Herman are in 1976 The concept of public key cryptosystem was proposed in , It is a great invention of modern cryptography , It will also provide a new direction for cryptography . The process of data encryption is to encrypt plaintext through the encryption system , Change the plaintext into ciphertext according to the encryption algorithm . 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 , for example ： Link encryption 、 Node plus 、 There are three ways of end-to-end encryption . There are many encryption algorithms for storage encryption , At present, the most commonly used algorithms are DES Algorithm 、RSA Algorithm 、PGP Algorithm etc. .

With the frequent occurrence of information security accidents , People also pay more and more attention to the technological innovation and innovation in the field of data security . The rapid development of science and technology has not only brought many conveniences to people , And also makes the means of hackers emerge in endlessly . As report goes , Finland 10 A little boy of , Although I don't have my own Ins account number , But it can delete user comments of all posts , He's hacked in Ins The youngest person . unimaginable , Children of such an age , It has reached such a state . Recall 10 I am , I feel inferior to myself ！ The above phenomenon has brought us a warning , Nowadays, hackers tend to be more and more instrumental , It can be said that a person who doesn't understand computers at all , Maybe just click a tool button , Can bring immeasurable losses to an enterprise , A stricter focus is more likely to bring life safety to everyone . This is not alarmist , Data security is no longer just an internal problem of a company , Or social stability , A major issue of national prosperity ！

Traditional encryption technology , It is also the infrastructure of network construction of enterprises and institutions , A firewall 、 Intrusion detection 、 Anti virus , Of course, these are far less than the current technological innovation . New encryption technology also came into being , For example, host monitoring , Document transparent encryption and decryption technology ,SDC Sandbox concept and other technologies . Document encryption adopts application layer transparent encryption technology, commonly known as hook transparent encryption technology . This technology originated from win98 Time , Later, along with windows2000 And it's popular . Is to combine the above two technologies （ application layer API and Hook） Combined . adopt windows Hook technique , Monitor the opening and saving of files by the application , When opening a file , First convert the ciphertext and then let the program read it into memory , Make sure the program reads clear text , And when it's saved , Then encrypt the plaintext in memory and write it to disk . application layer APIHOOK Encryption technology , It is characterized by simple implementation , The disadvantage is poor reliability , Super slow , Because you need temporary files , It's also 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, it feels very good , For the original blank Market , This banner has really moved many enterprises . and SDC The sandbox concept is developed on the basis of the former , Each filter layer only does what they are best at , So it's very stable , Fast , Reliable Performance , There is no problem .

Data encryption technology is the key to the prosperity of enterprises , Social stability, , A necessary complement to national security ！
