Abstract: In order to overcome the low security of privacy data in wireless sensor network, this paper proposes a new encryption and decryption algorithm for privacy data in wireless sensor network based on dynamic key. In this method, the dynamic key pool update mechanism is introduced to effectively avoid node leakage. At the same time, the authentication and update mechanisms are further introduced to increase the reliability of information sources. The integrity of data is artificially destroyed by introducing data disturbance. At the same time, the privacy data of wireless sensor network is encrypted according to the new key distribution algorithm in the process of data exchange. According to the requirements, specific algorithms are called to perform dynamic decryption to meet different business scenarios. The experimental results show that the key leakage probability is always below 0.10%, and the execution efficiency is significantly higher, up to 99%. The cost of the four algorithms is the lowest, with an average of 194,600 yuan. The effectiveness and superiority of the proposed method are verified.

Keywords: dynamic key; wireless sensor network; privacy data; encryption and decryption algorithm; node leakage; reliability of information sources; data disturbance.
