摘　　要：为了解决信息加密中硬件加密效率较低、软件加密安全性不足的问题,设计了一种基于区块链和高速密码卡的软硬件结合加密系统。系统在数据加密前增加了信息准备步骤。通过去中心化的区块链对待加密信息进行处理,将计算机的硬件特征引入签名验签,不通过第三方CA机构即可达到可信的目的。加密系统避免了密码资源暴露在网络中,提高了效率,改善了用户体验,增强了点对点通信的安全强度。In order to solve the problems of low efficiency of hardware encryption and insufficient security of software encryption in information encryption,a combined software and hardware encryption system based on blockchain and high-speed cryptographic card is designed.The system adds a new information preparation step before data encryption.By processing the information to be encrypted through a decentralized blockchain,the hardware characteristics of the computer are introduced into the signature and verification,the purpose of trustworthiness can be achieved without going through a third-party CA institution.The encryption system avoids the leakage of cryptographic resources in the network,increases efficiency,improves user experience,and enhances the security strength of peer-to-peer communication.
