Description

Technical Field

[0001] The present invention is a method for wireless communication in a classified environment, especially for information encryption and multi-channel transmission methods. Background Art

[0002] With the rapid development of industrial technology, more and more automated devices and intelligent devices are widely used in production. Most of these devices have the functions of real-time information processing and real-time information transmission. However, in some classified environments, it is not allowed to directly transmit classified or sensitive information using commercial wireless communication technology to prevent it from being illegally intercepted or deciphered. Therefore, these requirements restrict the use of advanced devices in classified industrial environments.

[0003] The wireless communication transmission system in a classified environment decomposes information into information fragments. After decomposition, the information fragments are reorganized according to the classification level, scrambled codes are added, and the order is disrupted to form data packets, which are then transmitted to the channel for channel encryption. The channel selection control unit transmits the data packets that have undergone two-level encryption through one or more channels according to the channel encryption algorithm. The channels include various wireless channels and wired channels. At the information receiving end, the data packets are decrypted on the channel, and then the scrambled codes are removed from the data packets in turn, and the information fragments are separated and reorganized. Finally, the information is sent to the destination, completing the information transmission. The information encryption and channel encryption designed in this system can prevent the data from being completely intercepted, and each data packet is a combination of information fragments containing scrambled codes without logic, thus eliminating the hidden danger of the transmitted information being deciphered. Summary of the Invention

[0004] The purpose of the present invention is to provide a system and implementation method for two-level information encryption in a classified environment.

[0005] A method for wireless communication in a classified environment, characterized by including the following steps:

[0006] Step 1: Import the information to be encrypted into the information processing unit;

[0007] Step 2: Set the classification flag, and encrypt the information according to the classification level of the transmitted information, that is, decide to select one or two layers for encryption;

[0008] Step 3: Encrypt the information to be encrypted through the information processing unit. The two-layer encryption is as follows:

[0009] (1) The information processing unit decomposes the information into information fragments, adds scrambled codes to the information fragments, and disrupts the order according to the rules to form data packets of different sizes;

[0010] (2) Encrypt the data packets according to the encryption rules;

[0011] Step 4: Send the encrypted data packet to the channel selection control unit. The channel selection control unit checks the information classification identification bit to determine the classification of the transmitted information. Then, one or more channels are selected according to the information classification to form a logical transmission channel. The transmission methods include:

[0012] (1) Select the same or different time periods for multiple encrypted data packets to transmit information on different channels;

[0013] (2) Select one or more channels to form a logical transmission channel to transmit multiple data packets simultaneously or at different times, and the channels are segmented and replaced during the transmission process;

[0014] Step 5: Set the channel switch flag before channel transmission;

[0015] Step 6: Before the channel transmits the data packet, determine whether the environment is suitable for transmission; if it is determined that the environment is suitable for transmission, transmit in a timely manner; if it is determined that the environment is not suitable for transmission, suspend the transmission and repeat Step 6 after a set time;

[0016] Step 7: Send all the segmented and encrypted information in sequence;

[0017] Step 8: After the information receiving unit receives the signal, it processes the signal and then merges the information. The transmitted information reduction unit decrypts and removes the scrambling code to restore the original information and transmits it to the information sink for use.

[0018] The multiple channel paths of the channel selection control unit include Bluetooth, infrared, laser, mobile network or wired network.

[0019] The advantages of the present invention are as follows: The information to be transmitted is encrypted in two levels. At the information source end, a computer is used to perform character-level decomposition on the information to be processed to form data fragments. Then, a scrambling code is added to the data fragments, and the data fragments are adjusted according to the encryption algorithm to form data packets of different sizes to complete the first-level encryption. Then, the second-level encryption is completed through the encryption algorithm. The computer transmits the data packets to the information path selection unit through the Ethernet port. According to the classification identification information of the wireless environment, one or more wireless channels are selected to transmit the information. During the information transmission process, different channels can be selected to transmit the data packets at different times, so as to realize that the data packets formed at the information source are transmitted through multiple wireless paths (different frequency bands, different channel modulation and coding methods). Finally, channel information decryption and information source decryption are performed at the information sink end to realize the secure and reliable transmission of information.
