In order to achieve the balance between informatization and security in the process of using the Internet of Things, quantum secure communication technology and its application in the industrial Internet of Things were proposed. The use of quantum secure communication can effectively solve the security problems of devices, and can solve the security problems encountered in the distribution of quantum keys through endogenous security means. Secondly, aiming at the problem of massive access delay of IoT devices, this paper conducts software simulation tests. The simulation results show that the time delay of asymmetric encryption algorithm is longer than that of symmetric encryption algorithm, the time delay of asymmetric encryption algorithm SM2 is obvious, the time delay of symmetric encryption algorithm AES is longer than that of SM4 and XOR encryption method, and the time delay of XOR encryption method is the lowest among the three symmetric encryption methods. With the further increase of the number of terminals, The delay advantage of XOR encryption is more obvious. Conclusion: Quantum encryption has the characteristics of low delay and good stability in the working environment of IoT devices, which can effectively ensure the data security of IoT devices.
