摘要
由于合同数据对于安全性和保密性的要求较高,以及互联网中存在服务器攻击、数据截取等安全隐患,目前的合同管理系统无法充分利用互联网的优势实现全流程的线上操作,尤其是身份认证和合同签订两个步骤难以实现.为了实现合同管理系统在公网服务器运行以及线上完成公司身份认证和合同签订,本论文设计并实现了一种基于私有链技术的合同管理系统.首先提出了公司数字认证中心的设计理念,用于管理公司的数字信息并参与公司身份认证;然后设计了合同管理系统和私有链系统的实现方案,最后介绍了系统实现中的技术要点.实验结果分析表明,该管理系统可以在线上实现合同管理的全部流程,提高了合同管理的效率.
Due to the high requirements for security and confidentiality of contract data and the potential security risks in the Internet,the current contract management system cannot fully utilize the advantages of the Internet to achieve online operations.Identity authentication and contract signing are technical difficulties in online operations.In order to realize the contract management system running on the public network server,and complete the company identity authentication and contract signing online,this study designs and implements a contract management system based on private chain technology.First,this study proposes the design concept of the company’s digital authentication center,which is used to manage the company’s digital information and participate in the company’s identity authentication;then it designs the implementation scheme of the contract management system and private chain system,and finally introduces the technical points in the implementation of the system.The analysis of experimental results shows that the management system can realize all the processes of contract management online,which improves the efficiency of contract management.
