An Research Security Based On Network Sale Manage System

This paper is about a Research Security System based onNetwork Sale Manage System. It describes popular encryption methodwe use at present time. In network ages, we send or receive largenumber of information through the network every day. But networktransmission has many unstable factors due to the openness of theinternet. With the network development and the share resource online,the data security has become a very important issue, thus, theencryption method plays a key role in the system.This text studied theories for the Date Security Based onNetwork Sale Manage System, has analyzed the present data securitytechnology merit and the limitation. The idea and the method ofwhich the present data security technology that has a lot ofmaturity is worth studied, but simultaneously the computer networkdevelops unceasingly, the data sharing universality and are the datasecurity a urgent matter, whether the data security relationship systemlife and death.Though the present attacks the method diversifiesunceasingly, this request data security algorithm is improving and inunceasingly the consummation.and expound the safety project of thedata security is divided three layer in the network sale system:1. Using the technology of physical firewall protect for the systemsecurity in the network sale.2. For the interior system data security, we introduce to thehoneypot technology and VPN technology, deeply protecting theinterior system data security.3. Using the multi-protecting, safeguard,try out find the means forthe data security in the system develop processing.In addition, the Taishan PengFei the limited company old sale system not to be able to deal with the service demand which thecompany grows day by day, out of the managerial class for the oldsystem, and ofen make large iperating mistakes, so having to usethe manual house-keeping operation every day, and bring many matterto the work is not convenient.This network sale system has increasedthe data capacity, when we study the data security ,discoveredthrough use prevented the overflow attack the method causes thesystem the data to be safer.In developing the system,we emphasis principally for the userdialog and output message,distinct type and limited of the datasecurity, insure each the function in this system is well.And found themessage manage machinery to achieve the goal of thecorporation,this is a part or a sub-system in the network sale managesystem.This text, based on the research of the theories and technologiesrelated to Network Sale Manage System, analyzes the present datasecurity technology's advantages and disadvantages. The idea andthe method of which is worth studying, but the universally date-sharingand the data security become urgent matters as PC network developssimultaneously and unceasingly. With the various ways of attack to PC,it requires constantly improving on data security algorithm. Inaddition,Taishan Pengfei the limited company's old system is not ableto deal with the service demands which increase everyday, and it oftenhas operation mistakes due to the overload work. The company has touse manual house-keeping operation and this brings a lotinconvenience to work. This network has increased the data capacity.And we could make the data in the system safer by applying methodsto prevent the overflow attack during our research to the data security.Therefore, this text mainly discussed how to encrypt on the datein the network sale system. It also explains the function of the encryption technology of the threshold generator and what protectingrole the hideaway technology plays on the date security in the networksale system.
