On The Digital Signature Applied Research In The Online Approval System

Digital signature techniques and algorithms are discussed in detail in the paper. The digital signature technique is one of the kernel techniques of network business security, and the data encryption technique is the basis of the digital signature technique. The digital signature provides a digital authentication method to resolve many problems about security, such as forgery, disavow, imitation and juggle, and is also used to the authentication of both sides of the communication. Humans usually add a segment of digitals into the digital message to realize the digital signature by using encryption the message. The author made RSA data encryption algorithm the basis of the digital signature. In the paper, the audior discussed RSA algorithm comprehensively and especially made proper improve on a few segments of the algoridim.The first chapter of this paper introduce the development of electronic government a flair, Second ,we will introduce the data encryption technique; The third chapter discusses the digital signature technique and arithmetic; The fourth chapter discusses the digital signature technique based on the RSA encryption arithmetic ; The fifth chapter analyze particularly that the digital signature technique based on the RSA encryption arithmetic is used widely in network examine and approve . In the end , the sixth chapter is the summary the whole paper.
