Research on Distributed Database Encryption Storage Based on Wireless Sensor Network Clustering Strategy

分布式数据库加密存储方法未分簇网络节点,存在加密、解密及存储效率低的问题,为此提出基于无线传感网络分簇策略的分布式数据库加密存储方法。首先分析分布式数据库在计算机网络中的结构体系,基于无线传感网络分簇策略对计算机网络节点进行分簇;实现分簇后,构建加密存储模型,通过该模型对分布式数据库中的数据实行存储、加密、密文分发、解密、获取明文等流程,最终实现对分布式数据库加密存储的研究。仿真分析结果表明,用该方法加密750个数据属性集时,耗时在15 s以内,解密耗时在12 s以内,存储耗时3.8 s~6.0 s之间,验证了该方法的高效率与实用性。

The distributed database encryption storage method does not cluster network nodes,and has the problem of low efficiency on encryption,decryption and storage.Therefore,a method of distributed database encryption storage based on wireless sensor network clustering strategy is proposed.Firstly,the structure of distributed database in computer network is analyzed,and computer network nodes are clustered based on wireless sensor network clustering strategy.After clustering is realized,an encrypted storage model is constructed,through this model,the data in the distributed database are stored,encrypted,ciphertext distributed,decrypted,plaintext-obtained,etc,and finally the research on encrypted storage of distributed databases is realized.The simulation analysis results show that when 750 data attribute sets are encrypted by using this method,it takes less than 15 s,the process of decryption takes less than 12 s,and storage takes 3.8 s~6.0 s,which verifies the high efficiency and practicability of the method.
