摘　　要：为了改善物联卡交易流转中存在的违规现象,提出了一种基于区块链和安全终端的物联卡交易管理系统。该系统由区块链子系统、安全终端子系统、其他辅助子系统组成。安全终端通过摄像头和可视化界面完成二维码数据采集,通过搭载SE-SIM对数据进行密钥管理和国密算法加密,通过使用数据库技术协助交易场景逻辑实现。区块链系统对外提供REST风格API接口,通过与辅助系统中的安全平台交互完成解密操作。该系统同时保证了链上账本交易和上链过程中端到端的数据有效性。Aiming at improving the irregularity phenomenon in current IOT-card transaction process,an IOT-card transaction management system based on blockchain platform and security terminal is put forward.This system includes a blockchain subsystem,a security terminal subsystem,and an assistant subsystem.Security terminal executes QR code data collection by camera and UI,preserve private key and executes international encryption with SE-SIM,and use database technology to assist realizing contraction scenes.Blockchain system privode REST style APIs,and realize decryption by communicating with the security platform in assistant system.The data validity of both on-chain ledger and end-to-end process are guaranteed in this system.
