Digital Signature Technology In E-government Applications

E-government as electronic information technology and management organically, become the contemporary the most important area of informatization of one. E-government mainly divided into three types:G2G (intergovernmental e-government); B2G (government-between e-government business organization), C2G (government-among citizens e-government). Intergovernmental e-government information communication mode is increasingly many government adopted, the procuratorial organs office handling information platform already more and more be adopted by the procuratorial organs at all levels, how to guarantee the fairness of case is related to the case, the party and country's major issues, this paper discusses the procuratorial organs e-government system is for B2G way.This article from the broad information technology safety begin to discuss how to guarantee, began from information security password of the technical analysis, again for encryption technology in digital signature technology of concrete research, from the derivation of a digital signature principle that elliptic curve cryptosystem (ECC) of concrete research. And now widespread public key cryptosystems mathematical foundation, realizing the principle and performance comparison.The principle of digital signature technology of elliptic curve cryptography compared with other has strong superiority, its application in future immeasurable, this paper will focus on is based on elliptic curve digital signature algorithm (ECDSA) in procuratorial organs e-government application. Based on ECC fast point multiply algorithm to optimize and improve the ECDSA efficiency and safety of digital signature, and will have been optimized ECDSA applied to XML digital signature scheme, finally ivr scenarios in procuratorial organs of electronic government affair work handling information platform has been applied in.
