Abstract


As information technology and computer networks in all areas of society-depth applications, office automation has become a trend and direction of development, electronic document has slowly replace the traditional paper-based documents into the various areas of office, brings convenience at the same time the problem of how to ensure the security of electronic documents is becoming increasingly urgent. Electronic signature technology is put forward in this context, and the field of information security and computer applications research focus. USBKey hardware device is a USB interface. Built-in microcontroller or smart card chip, directly from the system and hardware level to provide security protection to ensure that critical information is safely stored in hardware devices. To use a good storage USBKey and password performance, I can use it for electronic signature certificates and private keys carrier, which can effectively ensure the uniqueness and security of the personal signature. Multiple digital signature is a digital signature, the signature having multiple signatures Multiple makes this technology can be widely used in many fields. More systematic study of the significance of the multi-signature, background, on this basis will be multiple electronic signatures into USBKey. The paper combines the practical application of environmental requirements of the electronic signature, document flow technology and multi-signature technology, combined with the ActiveX control technology and cryptography knowledge, research and implemented based on the electronic signature systems USBKey. Electronic signature system and a useful exploration of the application, with high practical value and good market prospects in information security concern. This paper first introduces the entire project background and basic knowledge of the electronic signature and document integrity, stamp, security, multi-signature features three deficiencies existing systems, the research direction and research ideas. The second part of modern cryptography, PKI and digital signature technology are described in detail, and provides a good support for the application of these technologies in the system. Third part of the first part of the traditional electronic signature three deficiencies, combined with ActiveX controls, USBKey electronic signature security problem and multiple digital signature technology, design a new key technology solutions; part of the collection of the third part of the key technology research results on the basis of analysis of the electronic signature functional requirements from the signature generation and management module, the seal stamped with the authentication module, Word embedded module system design; gives a detailed description of each module of the program to achieve. End of the article on the performance of the system with a comprehensive analysis and follow-up research direction.
