Research on Network Data Security Storage Optimization Management

Abstract

Due to the variety of data used by the network, data storage is classified and encrypted. The traditional storage method mainly uses the data feature to select a key. When the amount of network data increases, the key appears to be duplicated, resulting in a problem of low security of data storage. A secure method for network data storage with improved keys is proposed. The cluster head is optimized and transmitted based on the layer cluster routing protocol, and a dynamic key is introduced in the data transmission process, and the key between the network data storage nodes is set by using the chain key generated by the hash function. The Chen hyperchaotic system is used to obtain the random key of the network data storage, the modified bits of the random key are planarly coded, the context and decision of the data storage are obtained, and the MQ arithmetic coder is used for entropy coding to generate the corresponding data storage compression code. The stream is fed back to the output of the Chen hyperchaotic system and the new data storage key is output. The simulation results show that the improved storage method effectively increases the security of data storage.
