物联网大数据有效信息的加密存储系统设计

Design of encrypted storage system for effective information of big data in internet of things

传统的加密存储系统对物联网大数据进行加密存储时,工作效率很低,短时间内能够加密存储的物联网数据节点极少。为了解决上述问题,提出了一种新的物联网大数据有效信息加密存储系统,对系统的硬件与软件进行了重点设计,采集器选用的芯片为TTSAD251芯片,能够扩大采集范围,处理器中设定了多个内核,降低系统功耗,存储器选用SPRTAN-2芯片作为结构芯片。软件工作由采集物联网数据由有效信息、建立加密文档和物联网大数据有效信息存储三部分组成。为检测系统工作效果,与传统系统进行实验对比,结果表明,给出的加密存储系统能够将物联网大数据有效信息的存储范围提升20.58%,工作效率提高5.64%。

Traditional encryption storage system is inefficient when encrypting and storing large data in the Internet of Things,and few data nodes can encrypt and store data in a short time.In order to solve the above problems,a new encrypted storage system for large data in the Internet of Things is proposed.The hardware and software of the system are mainly designed.The chip chosen by the collector is TTSAD251 chip which can expand the acquisition range.Several cores are set in the processor to reduce the power consumption of the system.SPRTAN is used as the memory.The 2 chip is used as the structure chip.The software work consists of three parts:collecting effective information of Internet of Things data,establishing encrypted documents and storing effective information of large data of Internet of Things.In order to detect the working effect of the system,comparing with the traditional,system the experimental shows that the encrypted storage system can increase the storage range of large data and effective information of the Internet of Things by 20.58% and the working efficiency by 5.64%.
