UWB wireless transmission security and reliability assurance technology
Ultra Wide Band(UWB)wireless transmission security and reliability technology is a critical component of UWB communication systems.In this paper,after briefly describing the design of UWB communication systems,we address the shortcomings in existing UWB communication protocol mechanisms regarding security and reliability.Leveraging the support of the DW1000 RF chip's channel sampling circuit,we establish an adaptive mechanism for channel quality assessment,an access mechanism based on frame filtering,and a high-reliability transmission mechanism based on ACK-based retransmission.Additionally,we propose a lightweight AES-128 dynamic encryption algorithm to enhance the security and computational efficiency of UWB transmission.Experimental results under laboratory conditions demonstrate a significant improvement compared to the original method,with zero packet loss and error codes.The average processing time for encrypting and decrypting plaintexts of 10 KB is reduced by 13.5 ms.Moreover,the ciphertext's information entropy is closely approximated to the original method.Consequently,the UWB security and reliability technology proposed in this paper exhibits substantial enhancements in various system performance aspects compared to existing UWB wireless communication mechanisms.
