Abstract

The invention discloses a system for realizing digital signal encryption transmission. The system can generate a secret key according to personnel information of a user, so that the secret key has the uniqueness and the complexity; in the digital signal encryption and decryption processes, the bit operation is performed with the personnel secret key and a first random digital signal through a plaintext digital signal to obtain a first ciphertext digital signal; meanwhile, the personnel secret key and the first random digital signal are subjected to bit operation to obtain a second random digital signal; the obtained second random digital signal and the first ciphertext digital signal are subjected to bit operation to obtain a second ciphertext digital signal; finally, the second ciphertext digital signal is subjected to inverting bit operation to obtain an original plaintext digital signal. The problems of poor confidentiality and low security of the digital signals are solved; the cracking difficulty is greatly enhanced.

Description

Technical field [0001] The invention relates to a system for realizing encrypted transmission of digital signals. Background technique [0002] The development of information network technology has provided great convenience for people. But at the same time, cyber crimes are also increasing, and information security issues have gradually become the focus of people's attention. At present, with the popularity of remote management methods for high-end servers, it is becoming more and more common to use clients to remotely manage servers. Compared with the general website login authentication mechanism, the server login authentication mechanism has higher security requirements. For example, in the process of direct data transmission between the client and the server, some key data will be leaked in plain text, such as the user name and password of the server administrator. Therefore, encrypted transmission is required. [0003] Data encryption, also known as cryptography, ref...
