The traditional IoT multi-device communication encryption module has insufficient defense capabilities, and often affects the connectivity of the IoT network. Therefore, the paper optimizes the design of the encryption module in the multi-device communication of the Internet of Things. When the amount of information is large, the symmetric key is selected for the encryption design, and the key distribution terminal splits the symmetric key and distributes it to the sending and receiving unit separately.When the amount of information is not large, an asymmetric key is selected, and the designed asymmetric key will be directly transmitted to the sending and receiving unit. The sending and receiving unit holding the key can download the communication information of the Internet of Things multi-device communication after successful joint authentication at the key authentication end. The experimental results show that the designed encryption module has strong defense capabilities and has a small impact on the connectivity of the Internet of Things network.
