Research on Wireless Encrypted Communication Based on Multi-Channel Transmission

With the development of the information age and the popularization of the internet, the ways of obtaining information are becoming increasingly rich, and the users' information security awareness is also constantly improving. The secure transmission of information has gradually become an inevitable requirement and tendency. Currently, most of the encryption algorithms utilize single-channel encryption for transmission, and sophisticated algorithms are mostly used for commercial purpose, which are not very economical for ordinary users. Besides, no matter how complex the encryption algorithm is, there is always a risk of being deciphered. Furthermore, once some commercial or industrial confidences are hijacked and deciphered, it will cause unpredictable losses. This paper proposes a wireless encrypted communication method based on multi-channel transmission. The proposed method integrates “unpacking, multi-channel transmission, combining” operations on transmitting data, by applying corresponding algorithms. The data is transmitted in the form of “fragments”, which increases information entropy during the transmission process, and then improves the security of information transmission. Experimental results show that the method proposed has obvious advantages compared to the traditional data encryption transmission methods. At the same time, it provides a new low-cost, easy-to-operate solution for secure information transmission.
