摘要
近年来,电子政务的普及带动了不动产业务办理中柜面手工文书签署方式向无纸化电子签署方式的转变,随之而来的是电子签署中对签名人身份认证和签名密钥安全性问题。对此,设计一种用于柜面文书签署场景的不动产业务办理柜面无纸化签署系统,系统集成于不动产一窗受理平台中,由客户端服务器、身份认证服务器、协同服务器构成,实现无纸化签署相关服务功能。依据对系统中关键技术的研究,提出了一种基于SM2的协同签名方案。方案中融合了对签名人身份的认证,运用PBE基于口令的密钥算法思想和门限密码学密钥分割思想提升密钥安全性。实践表明,该系统能够实现不动产柜面无纸化文书签署,提升不动产柜面业务办理工作效率,并为不动产业务日后的线上化改革、服务融合提供了建设基础。
In recent years,the popularization of e-government has led to the change from the manual signing method of over-the-counter documents to the paperless electronic signing method in the processing of real estate business,followed by the issue of the identity authentication of the signer and the security of the signature key in the electronic signature.In this regard,design a paperless signing system for handling real estate business in counter document signing scenarios.The system is integrated into the real estate one-window acceptance platform,and consists of a client server,an identity authentication server,and a collaboration server to achieve paperless.Sign related service functions.The key technologies in the system are studied,and a collaborative signature scheme based on SM2 is proposed.The scheme integrates the authentication of the signer′s identity and uses the PBE passwordbased key algorithm idea and the threshold cryptography key segmentation idea to improve the encryption.key security.Practice has shown that the system can realize the signing of paperless documents at the real estate counter,improve the work efficiency of real estate counter business processing,and provide a construction foundation for the online reform and service integration of real estate business in the future.
