The Research And Application Of Digital Signature

The computer and network technology development bring people into the information society,then come with the information security issues.Digital signature technology plays an irreplaceable role in the fields of identification and authentication, data integrity,anti-repudiation and so on,which has a very wide range of applications in e-commerce and e-government.Because the study of digital signature technology was relatively few in the enterprise information system,this paper is aimed at the application of digital signature technology in the electric power enterprises,made a deep study of the current information security and digital signature fields related technologies,combining the security requirements in the electric power enterprise information system,give the specific solutions for the enterprise information system applications according to the different information system requirements.Realized the digital signature technique in LongYan electric power bureau setting management system of protective relaying and the online bidding system of hydroelectric for China HuaDian,the test results achieved the expected goals and ensured the confidentiality,integrity,and non-repudiation of the information.
