The Research Of The Security In Electronic Signature System Based On PKI Technology

At present, a lot of secret information as a part of the electronic document transferred in internet, which attracts significant coverage from people who often use electronic document.This Paper relys on electronic seal system of CVICSE software corporation, investigates the security technology.Public Key Infrastructure(PKI) is the suit of safety Infrastructure which offer identity authentication and distinguish, assure information confidentiality and integrality, and prevent the sent or received information from denying under the open network environment. PKI has already become major technology in the safety certification field of information at present.As an important component of E—Government system.electronic signature system provides the function service for E. Government System, and basically solves the problem of stamping the seal and signature in electronic document, distinguish the identity of operation, ensure the electronic document authenticity, integrality, confidentiality and cannot denying. This is paper brought forward the safety solution of electronic system based on public key infrastructure, and analysed the design and realization of electronic signature system in detail.It is made use of figure document technology,information security technology, middle technology and computer network technology,achieves the function of document of seal execution, distribution,inception,reading,mimeograph,transmission and pigeonhole.It was taken place of the old transfer pattern by the modern electronic document transmission pattern.It is certificated the identity of user who mostly adopt the PKI security system ,auditinged the user's identity information and public key information and issued the figure certificate to the user by Certificate Authority.This paper investigate and analyse and compare the RSA arithmetic and the ECC...
