The new period encryption technology in the application the study of network security

摘要

With the rapid development of computer, network is also in constant development. A variety of network attacks and the corresponding means also breed, network security has become now the human network life about to ask. One of the most important methods to protect the network security is a data encryption, its application in computer network security greatly improves the security of network information transmission. One, Analysis of a, encryption technology With the popularization of computers and the widespread application, mankind has entered the information era, because of the important role of the network, once the network safety is threatened, leading to the occurrence of the fault is not working properly, or even network paralysis, will give people's work life brings the serious influence, set to make the whole society into crisis. Human factors mainly involve hackers and virus; non-human factors are mainly related to computer hardware failure and damage of the components, electromagnetic interference, natural disasters, etc.. Network security of people exchange information security risks is the most important computer criminals, process information exchanges often use loopholes to get and use information exchange and transmission process of leak data, and ultimately harm the fundamental interests of the majority of people, serious threat and harm the national security. Therefore, we must take effective security measures to maintain the security of network science. Encryption technology is a kind of active information security measures, and ultimately ensure data confidentiality. Is there a public key and private key two usual methods. The first method is the private key, because the key is the common recognition of both sides, so it can pass the same data key used for encryption and decryption, to ensure the safety of the computer. To make a long story short, the network information security is a very important and arduous task.
