Abstract

This paper combines Quantum Key Distribution (QKD) technology with the Beidou short message communication system to study the security and reliability of Beidou short message communication, so as to improve the security and reliability of information transmission. It proposes to use QKD to ensure the security of key distribution, and combines symmetric encryption algorithm to encrypt data, introduces timeout retransmission mechanism to improve the reliability of data packet transmission, and implements large packet splitting and recombination strategy to solve the problem of single transmission capacity limitation. The success rate of QKD and the integrity and efficiency of data transmission in various network environments are experimentally verified, which perform noticeably well especially in high packet loss rate environment. The advantages of QKD, timeout retransmission and large packet splitting under complex conditions are verified, and their prospects in practical applications are demonstrated.
