【摘要】：随着信息技术的快速发展,人们已经进入信息爆炸的时代,人与人之间的合作、竞争和信任都是以信息为载体,信息资源无疑是最宝贵的资源,一旦丢失则损失惨重。传统的信息记载方式无法证明信息所属,信息很容易泄露或丢失,人们生活在一个信息不完全可信的环境中,使得合法权益受到威胁。区块链作为比特币的技术核心,通过技术手段解决了人与人之间,以及人与系统之间的互信问题,为保护用户信息安全做出了跨时代的尝试。本文基于区块链技术思想设计了一套加密信息备份系统,并采用Node.js及相关组件完成了该系统的开发和测试工作。该加密信息备份系统的核心功能是帮助用户备份重要的文本信息,信息经加密后被存储到所有的应用节点,节点遍布全球,每个节点都拥有最新的完整数据拷贝。同时,本文对该系统的便捷性进行了改良,设计并实现了用户私钥加密备份和文本信息的安全发送等功能。本文通过设计基于P2P网络的分布式数据存储策略,保证了用户备份的文本信息不会丢失;采用基于椭圆曲线系列算法的签名验证技术,实现了信息的所有权认证;采用安全的加解密技术,保证了用户信息的安全;设计了有效的共识机制,保证系统正常运行;设计了可远程访问的应用节点,使得用户随时随地可以操作文本信息。本文通过对区块链技术的应用创新,证明了区块链在去中心化的文本信息管理上的技术可行性和安全可靠性。
[Abstract]:With the rapid development of information technology, people have entered the era of information explosion, the cooperation between people, competition and trust is based on the information carrier, information resource is the most valuable resource, once the loss suffered heavy losses. The traditional methods can not prove that the information recorded information is easily leaked or information lost, people live in a trusted environment with incomplete information, the legitimate rights and interests are threatened. As the core technology of bitcoin blockchain, through technical means to solve the mutual trust between people and people, as well as the problems between human and system, try to make a cross age in order to protect the security of user information. The idea of block chain technology based on design a set of encryption information backup system, and using Node.js and related components to complete the system development and testing work. The core function of the encrypted information backup system is to help To help users to backup important text information, the information is stored in the application after encrypting all nodes, nodes around the world, each node has a complete copy of the latest data. At the same time, the convenience of the system is improved, the design and implementation of user private key encryption backup and security of text information transmission in this paper, through the design function. Based on the distributed data storage strategy of P2P network, the text information is not lost by user backup; signature verification technology based on elliptic curve algorithm, realization of information security certification of ownership; using encryption technology to ensure the security of user information; design a consensus mechanism effectively, guarantee the normal operation of the system; the design and application of remote access node, so that the user can manipulate text information whenever and wherever possible. In this paper, through the application of the technology innovation chain block It proves the technical feasibility and safety reliability of the block chain in the de centralization of text information management.
