Research On Encryption Storage And Retrieval Technology Of IOTA Distributed Ledger Data

Block chain's rapid rise in recent years,a distributed storage technology,it has advantage of decentralized and tamper-resistant and open,to get attention from all walks of life,block chain technology in rapid development,the support of the country,the development community of active and enterprise's attention from all walks of life provide huge power to block chain development.However,the traditional blockchain has many shortcomings in data storage and retrieval,such as slow upload speed,no support for private data storage,high cost of massive data operation,no support for field query,etc.In order to solve the problems,this paper adopts IOTA distributed ledger technology.IOTA,as the third generation of blockchain products,solves the core problems of traditional distributed ledger such as scalability and cost,and becomes a hot blockchain product in the era of industrial Internet of Things.This paper describes the development process of blockchain,combined with the needs of the industry in different periods,analyzes the iterative process of blockchain technology.In the research and analysis of the existing block chain in the data storage drawbacks,put forward a solution.The main research work of this paper is as follows:1.In this paper,the influencing factors of TANGLE,the underlying consensus structure of IOTA distributed ledger,are studied.TANGLE simulation model proposed by the official community is used for experiments,and the experimental data of TANGLE are evaluated through data mining method,and the factors affecting the development of TANGLE are analyzed.The research method adopted in this paper provides a new way for IOTA research,and has certain reference and guiding significance for IOTA mechanism and performance research.2.While analyzing the influencing factors,the expansion coefficient A,the main influencing factor,is expanded in this paper.Combining the advantages and disadvantages of the two existing IOTA advanced trading selection methods,a segmented adaptive advanced trading selection algorithm is proposed,which can increase the system system energy as much as possible on the basis of ensuring the network security.3.This paper analyzes the disadvantages of the traditional chain structure blockchain,such as small throughput,large transaction cost and low data storage operability,and proposes a data encryption storage and retrieval scheme based on IOTA distributed ledger.IOTA distributed ledger is introduced to accelerate the speed of data linking and retrieval and ensure the integrity of system data.Masked Authenticated Messaging is used to authenticate the transmission,so that the upper link data is stored in the form of encrypted data stream.Enhance data storage operability by establishing indexing or data channel mechanism.
