Description

technical field [0001] The invention relates to the technical field of network information security, in particular to a network data encryption repeater. Background technique [0002] The security of network transmission data is an important security requirement. It is an important security technical means to encrypt the transmitted data and transmit it on the network after encryption to ensure the security of network transmission data. With the continuous development of computer technology and computer network, people have higher and higher requirements for the security of network data. Especially when data related to confidential information, personal privacy and public safety are transmitted on the network, data security is particularly important. [0003] Traditional data encryption schemes usually use algorithms such as AES to encrypt data, and the keys required by AES are distributed through algorithms such as RSA. Since the security of RSA is based on computational...

AI Technical Summary

Problems solved by technology

Since the security of RSA is based on computational complexity, with the development of computing technology, especially quantum computing technology, it poses a huge challenge to the security of traditional encryption algorithms based on computational complexity represented by RSA.

[0004] On the other hand, broadband computer networks such as Gigabit Ethernet put forward higher requirements on the efficiency of encryption processing. The encryption algorithm represented by AES is relatively complicated, and it is difficult to realize real-time encryption and decryption of Gigabit Ethernet data.
