Embodiment 1
[0032] The present invention provides a terminal control and secure communication method of the Internet of Things, such as Figure 1-5 As shown, the steps include:
[0033] S100: Number the IoT devices, generate the corresponding key according to the corresponding number through the back-end encryption server according to the key generation rules, and write the key into the corresponding key card in turn; Communication server address, communication key, encryption algorithm information;
[0034] During specific implementation, the key generation rules in S100;
[0035] The master key generation rule is to input the first security data, which is the root key, and input the second security data, which is the master key dispersion factor, and generate the master key through the DEA encryption algorithm;
[0036] The working key generation rule is to input the master key, input the function point number, and generate the working key through the DEA encryption algorithm.
