Abstract

In the information age of today, the development of network technology dissemination and exchange of information more convenient and faster, modern people have been surrounded in a variety of information among. Computer application software development greatly facilitated the process of development of office automation, information transfer, share and collect and office electronic closely together. More and more government agencies, corporations and individuals using the Microsoft Office and other office systems, achieved through electronic document information transfer documents, then discuss how to protect the security of electronic documents in question becomes increasingly urgent. Research secure electronic documents in the electronic signature system in the realization of great significance. Electronic signature system has broad application prospects at home and abroad about the electronic signature system technology has been more and more, and there are many manufacturers have done related applications products, companies and government agencies already have different ranges within Application. Electronic signature system applications to achieve a paperless office, is conducive to social protection, reducing waste of natural resources; improve the operational efficiency of the government and enterprises, and enterprise information for the government to provide the necessary tools and security services. This paper introduces the analysis of the electronic signature-related knowledge, the design and implementation of an electronic signature system. The main work is involved in secure electronic signature electronic signature based cryptography based, PKI system and an ActiveX control technology to make a lot of research, design and implementation of an electronic signature system. The system is based on the digital certificate system, the use of digital signature technology and ways to embed components implemented in WORD document signed and sealed. Users can use the system signature verification documents and signatures are true and complete non-repudiation signature views, while achieving document protection, as well as the signature production management. This paper is divided into four parts. The first part discusses the significance and background of electronic signature status quo and the main results presented herein. In the second part of the electronic signature system related to the theoretical basis of cryptography and PKI technology for a detailed introduction and description. The third part of the electronic signature system carried out a detailed analysis, and proposed the system design and implementation process. The fourth part of the rest of the system of electronic signature implementation techniques ECDSA digital signature technology and digital watermarking techniques are discussed and analyzed, and pointed out that these two technologies in the electronic signature system application prospects for our future research and practice work in the right direction. The author is a graduate student in reading period at the enterprise level involved in the development of digital certificate authentication systems, enterprise CA in UF NC system security applications and other projects, as dissertation writing provides an important practical basis.
