The Application Of Identity Based Digital Signature To MyAccount System

With the rapid development and popularization increasingly of the network technology, the building of handle official business networkedly in military affairs and the developing information safe become more and more important. The digital signature technology is the foundation and important guarantee of information safety theory and technology, when it is applied it to the handle official business network, it can offer the identity authentication service, authority control service, information insurance service, data integrality service and undeniable service, thus it can provide a safe environment for the MyAccount network office system.This thesis mainly analyzes and studies the digital signature technology application in the MyAccount handling official business network from the following four respects: The first part makes an introduction to the digital signature technology that explains the definition, the principle and wide application prospect of the digital signature technology, analyzes and compares about the digital signature algorithms in common use, and chooses the most safe and practice digital signature algorithm through studying; The second part analyzes the information safe, puts forward the PKI believe in the model suitable for the MyAccount handle official business network networked and finishes the design of the digital certificate system that is used actually; The third part regards believe in the model and digital certificate system as the foundation and the digital signature scheme designed as the core, realizes a digital signature system including two parts of the identity authentication subsystem and file transfer subsystem, makes the user security visit to the network file releasing system. Finally, based on the present state of development of the digital signature technology, the thesis puts forward the further research direction of the digital signature technology application in the MyAccount network office system.
