Digital Certificate-based Electronic Signature Technology Key Technologies Research And Application

The present era is an era of rapid changes in technology, along with the rapid development of science and technology, network technology has been in the field of socio-economic life has been widely used.Information security industry has been very sensitive and hot topic, the experts in the process of gradually understanding of PKI, the dedicated work of PK-based network security solutions research. Network of high-speed development of information that we have put forward higher requirements. April 1, 2005 "Electronic Signature Law" was implemented, the use of electronic signatures for transactions on the network behavior of the law, some laws and regulations require the original signature or seal must be in person to retain a written application documents, written notice of such acts, we can through the website with the agreement between the user, online. For e-commerce industry, the electronic certificate industry, the financial sector, as well as information security and software-related development of the market has positive significance.In this paper, based on the application of PKI digital certificates, for the government's public service areas of information security. In PKI cryptography and the principle on the basis of this paper, the application from the PKI, the PKI technology for the development of the current situation and the application to do an in-depth exploration and study, based on PKI and digital certificates in applied research direction, namely, the establishment of a "unified platform for secure authentication" and in Qingdao City Administration of Industry and in-line inspection systems for practical applications.PKI technology based on in-depth study, confidence in the existing network system based on the practical application of research, this paper presents an effective e-government security solutions for public services, the use of "digital certificates + Electronic Signature" model to PKI technology for industrial and commercial online inspection system. In this system, the main use of PKI digital certificate technology login authentication technology, digital certificate-based electronic signature technology. Among them, the design of electronic signature for the main content. The use of digital certificate authentication to ensure the authenticity of the user; the use of electronic signatures to ensure that the form of data integrity and non-repudiation of the main acts. Comprehensive use of a wide range of PKI technology for e-government to build a more rational, more convenient, more comprehensive security platform.PKI through theory, research and application of specific project design, summed up the application of digital certificates in a variety of technology and promote the development of PKI technology, strengthen the building of network security.
