Abstract: Aiming at the security problems of data monitoring, and forgery and tampering in the process of wireless communication network, this paper proposes a lightweight data encryption algorithm based on dynamic key, in which an authentication scheme combining with the characteristics of communication system is constructed. Firstly, the communication network structure is constructed based on encryption algorithm by using C/S security agent model. Furthermore, the data symmetric encryption and decryption are completed by using exclusive OR algorithm. In addition, adopting hash algorithm which can complete data integrity authentication, and reduce resource consumption in keys and message. The libmodbus open source libraries are employed to simulate the master/slave device communication, and simulation results show that the improved scheme ensures the synchronisation and accurate key updating, realises the self-organisation and management of the key. At the same time, the proposed algorithm has great advantages in resource consumption, compared with other algorithms.
