Abstract: The smart nodes in the expressway intelligent service area Internet of Things realizes the Ethernet communication protocol and wireless network communication protocol. This paper is concerned with the problem of data security between the smart node and the server. The study shows that, among different data encryption algorithms, DES encryption algorithm are suitable for encrypt data by embedded system. At first, the paper introduces the function of smart node and its hardware environment. Then, the data encryption software design is presented. At last, DES encryption programs and the encryption effect are tested in Internet of things smart node application. The test results show that the algorithm can be implemented stably in Internet of things smart node hardware platform. The encryption and decryption efficiency is better than the general algorithm. DES encryption algorithm improves security of the Internet of things smart node in network communication.
