Based On Single System Design Of Network Security Gate Command

Network safety is one of the most important investigations about information safety, and is also one of the hotspots in the field of studying information safety. It is a task of the network safety to make datas not to be destroyed,changed or leaked accidentally or evilly when the datas are being transmitted. At present a applied way is to encrypt the transmitted datas on nets. Encrypting datas depends on mellow data-encrypted technique.This article is based on the wide area network platform of Ertan Company, combines the demands of strobe sheet system in network and ensures applied data encrypting ways, systemic structure of the system, network operation system and network database system by attesting RSA identity, DES encrypting techniques, B/S and C/S system structure, the analysis and comparison between network operating system and network data base system. This article is designed strobe sheet system based on network safety on the Delphi stage. Delphi language is used to open up central contents, which are data encrypting module and code-unchained module, and the module that exchanges datas with background SQL Server.HTML language uses this central part to refer net page interfaces to the clients who is browsing informations.This article also expatiates in detail the holistic design and detailed design of the system, and discuss therotically the data base design, identity attesting and encrypting ways of the system. All these establish the therotical and actual base for the system. So the whole system has favorable maneuverability and can be suitable for different applied circumstance.The outcome of the system's running proves that the strobe sheet system of the network strobe sheet system designed in this artcle can fulfil the needs of sheet sending out, sheet feeding back or sheet managing ,etc. The implementary project in this article answers for the practical instance of Ertan Company rundle attempering, and is improved to be practical and feasible. This project settles substantial base for the contiuing building of infromationalized system in rundle attempering.
