According to the invention, a sender dynamic conversion unit is additionally arranged on the encryption device to form the dynamic encryption device, and a receiver dynamic conversion unit is additionally arranged on the decryption device to form the dynamic decryption device. Meanwhile, a sender route control output unit and a sender route control input unit are respectively arranged on the dynamic encryption device and the sender communication device to support a sender to dynamically select channel transmission; a receiver route control input unit and a receiver route control output unit are respectively arranged on the receiver communication device and the dynamic decryption device to support a receiver to dynamically select channel transmission, and the confidentiality and the safety of the whole communication system are further improved by using the modes of dynamic routing, information fragmentation and interference mixing; and the communication security is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a communication system which dynamically changes an encryption algorithm, a key, a communication channel and communication content during the communication process. Background technique [0002] Information encryption is a common means of information protection in the field of communication. The plaintext is encrypted using an encryption algorithm and a key, and then the information sender transmits it to the information receiver through the communication channel, and the information receiver uses the corresponding decryption algorithm to decrypt the ciphertext to obtain the plaintext of the message. In current communication systems such as figure 1 As shown, both communication parties generally use a certain encryption and decryption algorithm to encrypt information, and use a fixed communication channel for information transmission, and only valid information...

And once the cracking is successful, it means that all the information transmitted by the communication channel will be cracked into plain text, and the encrypted communication system loses the meaning of confidential transmission

[0004] The traditional fixed encryption method has deficiencies in the actual application process: first, it uses a fixed encryption algorithm and key, and the stealer can obtain the key information by continuously monitoring a large amount of information for comparison and verification, and once a certain communication information is stolen After the stealer tries to break through, the encryption algorithm and key will be mastered by the stealer, and the subsequent information transmitted by the communication system will be decrypted into plaintext by the algorithm, resulting in the loss of protection for all subsequent information; secondly, using a fixed communication channel, the stealer can Continue to eavesdrop on the entire information communication process and steal the ciphertext completely, which greatly increases the possibility of the full text of the information being cracked; finally, if only useful information is transmitted on the communication channel, it is easier for the stealer to obtain the original information and increase the chance of being cracked. dense probability
