【摘要】：电子合同的提出,打破了传统理念,合同生效的方式、时间和地点与传统合同存在很大的差异。电子合同作为电子文档有着非常显著的优势:电子合同可以在任何时间、任何地点签署;查询、存储合同也带来极大便捷性。通过详细的研究《中华人民共和国合同法》、《中华人民共和国电子签名法》以及《电子合同在线订立流程规范》等法律法规,并结合电子商务平台交易中的安全需求,分析了PKI/CA技术如何保证电子合同签署方身份的真实性,并通过使用电子签名技术确保电子合同的完整性、真实性和不可抵赖性,将电子合同系统日志记录和相关凭证有效的存储及取证,从而解决电子合同抵赖以及法律纠纷问题。本文首先详细地研究了电子合同系统的设计背景和意义,并充分的研究了国内外的研究现状,对信息安全领域的法律法规有比较深刻的解读。然后重点介绍和分析了电子合同系统的设计与实现所要用到的关键技术,包括PKI/CA、电子签章技术、可信时间戳技术以及人脸识别技术,为电子合同系统的实现提供技术和理论基础。最后,充分调研用户的需求,并作出需求分析,提出电子合同系统的概要和详细设计方案,主要包括使用的软件架构、系统功能设计、数据库设计、详细接口设计与实现等。在上述系统总体设计的基础上,本平台基于天威诚信完善的CA证书体系、可信时间戳服务等信息安全基础设施完成了一套有效的电子合同系统的实现并进行了测试。目前本平台已经进入试运行阶段,企业和个人用户可以登录本平台签署电子合同,取得了良好的效果。
[Abstract]:The proposal of electronic contract breaks down the traditional idea, the way of the contract taking effect, the time and place of the contract are very different from the traditional contract. Electronic contracts as electronic documents have a very significant advantage: electronic contracts can be signed at any time, anywhere; query, storage contracts also bring great convenience. Through the detailed study of the laws and regulations such as the contract Law of the people's Republic of China, the Electronic signature Law of the people's Republic of China and the online procedure for the Establishment of Electronic contracts, and taking into account the security needs of e-commerce platform transactions, This paper analyzes how PKI/CA technology ensures the authenticity of the signer of electronic contract, and ensures the integrity, authenticity and non-repudiation of electronic contract by using electronic signature technology. The electronic contract system log records and related vouchers are effectively stored and collected to resolve the electronic contract repudiation and legal disputes. In this paper, the design background and significance of electronic contract system are studied in detail, and the current research situation at home and abroad is fully studied, and the laws and regulations in the field of information security are interpreted deeply. Then the key technologies used in the design and implementation of electronic contract system are introduced and analyzed, including PKI / CA, electronic signature technology, trusted timestamp technology and face recognition technology. It provides technical and theoretical basis for the realization of electronic contract system. Finally, the author makes a thorough investigation and analysis of the users' needs, and puts forward the outline and detailed design scheme of the electronic contract system, including the software architecture, the system function design, the database design, the detailed interface design and so on. On the basis of the overall design of the above system, this platform has completed an effective electronic contract system based on the CA certificate system, trusted timestamp service and other information security infrastructure. At present, the platform has entered the trial stage, enterprises and individual users can log on to the platform to sign electronic contracts, and achieved good results.
