Network Data Encryption Technology based on Hardware Protocol and Algorithm

Abstract

In order to improve the security of network data transmission and avoid the leakage of transmission data, this paper proposes an enhanced data transmission security and reliability scheme, and design a new data encryption and decryption system using hardware encryption protocol and algorithm. The main function of the network hardware encryption machine includes the single chip microcomputer, FPGA and El interface; the main function of the single chip microcomputer is to enter the initial key, in which FPGA is responsible for generating the encrypted key stream; the E1 interface is responsible for receiving and transmitting data; the password system uses 63 bit Gold code, and using DS21348 register completes the level conversion of HDB3 and TTL, to realize the full duplex communication of encryption and decryption. Finally, the encryption system is tested, it can be found that the system can effectively complete the data encryption and decryption operations in the process of data transmission, and it can be converted into the plaintext ciphertext, and can also reduce decrypt the cipher text to ensure the security of information. The fuzzy chaos degree of system encryption and the accuracy of decryption are higher, which can weaken the intensity of attack and improve the reliability of the system.
