Abstract: The current ciphertext data encryption system of the Internet of Things (IoT) has some problems, such as long execution time and small probability of query-shared key. This paper proposes a new ciphertext data encryption method based on HECRT key management. CPU is used to calculate the password in the special engine, which can encrypt the relationship between the engine and other modules in ciphertext data encryption system. HECRT key management is used to construct the network model of the IoT, and the Chinese residual equation is used to realise the encryption method of ciphertext data of the IoT. The experimental results show that the throughput of the proposed method is more consistent with the SQL Server database, the execution time is lower than 0.35 s, and the probability of discovering Shared keys is higher than 80%, which can prove that the proposed system has strong usability and encryption capability.
