The Research And Designs Of Integrated Network Information Security Transmission System Based On The PKI

The integrated combat is one kind of new operational form in my armed force modern warfare, is increases of the battle efficiency and key of realizes the information. The integrated network is the safeguard which the integrated combat implements, it is one system network which is composed by the many local area network, each local area network separately is responsible for the duty of the corresponding module the combat safe guards, like artillery module, armored module, anti-aircraft module and so on. Each other must mutually pass on data, document and instruction in each local area network to guarantees the direction decision smoothly carries on.At present, this network mainly through adds the security machine to guarantee information safe transmission and so on simple status authentication, but also lacks the effective method in guarantee information the confirmation, the authorization, the secret and the integrity. Specially in the wireless network transmission, as a result of the transmission medium openness, causes its security to appear for is still important, how solves the network security becomes one extremely impatient question.The paper mainly discussed the PKI foundation technology knowledge and the concept,discussed the base knowledge and the basic principle of the modern cryptography. The article introduced and compared main algorithm characteristic, the speed, the encryption intensity of each kind of encrypt. Elaborated the public key system in the PKI system application: Digital envelope, digital signature, as well as digital certificate definition, form and use.The paper finally revolves the secret cipher system, established and realizes one security practical information safe transmission model. The model system structure mainly by the security system,...
