【摘要】：针对无线传感器网络多应用场景下异构数据的安全融合问题,提出了一种轻量级的安全数据融合保护方案,该方案可同时保障数据的隐私性、完整性和新鲜性。首先,以当前融合轮数和节点预置密钥作为哈希函数的输入,为节点更新每个融合周期的密钥;其次,采用同态加密技术,使中间节点能够对密文直接执行融合操作;然后,采用同态消息认证码,使基站能够验证融合数据在传输过程中是否被篡改;进一步,对明文信息采用编码机制,以满足多应用场景下异构数据聚集的使用需求。理论分析和仿真结果表明,该算法具有较好的安全性、较低的通信开销和更高的融合精确度。
[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.
