Study On Public Key Infrastructure Technology For E-Government Application

The electronics governmental affairs construction has already become the our country all levels government governmental affairs information-based target and the development trends, the information system that props up the electronics governmental affairs faces the serious and safe problem, the safe problem of the electronics governmental affairs system and the safe problem of the military, financial systems contain tremendous difference, it since exist the safe problem of appropriation, and then have the in great quantities public and safe problem.In numerous safe techniques, Public Key Infrastructure technique to the guarantee electronics governmental affairs system the information safety and the body confirms to have the special function, it has important function to the secret, reliability, integrity that the assurance system information deliver.Therefore, the research PKI technique is in the electronics governmental affairs system of application, have the bigger engineering to practice the leading meaning, can also promote related theories and techniques study, have the important technique theories meaning and engineerings to apply the value.This topic research with heavy celebrate the information industry development funds item the " the technique of PKI is in the electronics governmental affairs of application" of the city information industry bureau is background, the aim is at the technique of PKI that the quest matches the national technical specification in the electronics governmental affairs of the local area of application, to resolve current heavy celebrate the safe problem of information that the city electronics governmental affairs face.Mainly complete the following research work:(1) Analyze the safety of the electronics governmental affairs system, combine heavy celebrate physically, the aims at the electronics governmental affairs system information safety inside the city suffer from, putting forward the problem-solving counterplan project;(2)Owing to the analysis of the PKI system structure, related calculate way and applied characteristics, aim at the our country electronics governmental affairs system circumstance, put forward the PKI in the electronics governmental affairs system of applied project;(3) Study the numerical certificate standard, structure and code the technique, put forward the applied system structure of numerical certificate;(4)Apply the research result in heavy celebrate the south shore area of city to transact the automation in.Combine technique of PKI and numerical certificate systems are organic, make use of the electronics Company's seal system, improve that system.End, well worth mentioning of is, the improvement system of empress through usage, express the safety of that system better, can compare goodly safety, integrity and unique sexes of guarantee the system information.
