[Abstract]:In order to solve the problem of heterogeneous data security fusion in wireless sensor networks (WSN), a lightweight secure data fusion protection scheme is proposed, which can guarantee the privacy, integrity and freshness of the data at the same time. Firstly, the current number of fusion wheels and the preset key of the node are used as the input of the hash function to update the key of each fusion cycle for the node. Secondly, the homomorphic encryption technology is used to enable the intermediate node to perform the fusion operation directly on the ciphertext. Then, the homomorphic message authentication code is used to enable the base station to verify whether the fusion data has been tampered with in the process of transmission. Furthermore, the coding mechanism is used to meet the requirements of heterogeneous data aggregation in multi-application scenarios. Theoretical analysis and simulation results show that the algorithm has better security, lower communication overhead and higher fusion accuracy.
