基于区块链技术的非交互式密钥协商系统

Non-interactive Key Agreement System Based on Block-chain Technology

提出一种基于区块链技术的物联网信息非交互式通信方法及系统模型,通过Diffie-Hellman密钥协商协议和RSA签名认证,将区块链技术的分散网络特性应用于物联网通信中的去中心化,实现了物联网用户间端到端的安全通信,同时也保证了对第三方可信任机构的低依赖和解决IOT数据兼容问题,有效减少了物联网系统的运维成本。

A non-interactive communication method and system model of Internet of things based on block-chain technology is proposed.Through DH key agreement protocol and RSA signature authentication,the decentralized network characteristics of block-chain technology are applied to the decentralization of Internet of things communication,and the end-to-end secure communication between Internet of things users is realized.At the same time,it also ensures the low dependence on the third-party trusted institutions and solves the problem of IOT data compatibility,which effectively reduces the operation and maintenance costs of the Internet of things system.
