Research on Data Security and Encryption Technology in Network Transmission

Abstract

In the information age, data has become an important factor of production and social wealth, and even an important resource for competition among countries. However, the huge value of big data also makes it a key target of current network attacks. Data encryption technology is a kind of intelligent data security technology. It can set keys through protocols, ciphertext, passwords and other ways to achieve the encryption of data information and ensure its transmission security. The keys in these applications can only be deciphered by the data sender and the data receiver. At present, the data encryption technologies applied in network transmission mainly include symmetric encryption algorithm, asymmetric encryption algorithm, virtual network encryption technology, SSL protocol encryption and verification technology, link encryption technology and quantum encryption technology. If the corresponding encryption technology is reasonably applied to the network data transmission, its security can be effectively guaranteed.
