摘要
基于区块链技术,提出了一种新型的密钥生命周期演示设计方案.方案通过构建区块链网络,将密钥存储的职责交由各节点共同承担,相较于传统的中心化公钥系统能够提供更好的响应性能和抗干扰能力,同时分析了缺陷对公钥管理的影响进行了一定的技术改进,有效规避了能源浪费等问题.分析常见的针对公钥系统的攻击方式,证明了系统对攻击者通过欺骗节点干扰共识的达成和传播有着较强的抗干扰性.方案具有去中心化、集体维护、安全可信、可溯源和防篡改等优势.
Based on the blockchain technology,a new key life cycle demonstration scheme is designed.The nodes in the blockchain network share the responsibility of key storage.Compared with the traditional centralized public key system,it can provide better response performance and antiinterference ability by splitting the storage system into the constituent nodes of the network.This paper also analyzes the influence of defects on public key management,and makes some technical improvements to avoid energy waste and other issues.By analyzing the common attack methods on public key systems,it is proved that the proposed scheme has strong anti-interference ability to reach and spread the interference consensus of attackers through cheating nodes.The proposed scheme has the advantages of decentralization,collective maintenance,security and credibility,traceability,tamper proof,etc.
