The Information Safety Technologies Of The Research And Practice On Network-Based Design

In face of the individuation and diversification of customer'sdemands and the rapid changes on the international market enterpriseselnploy the network-centered il1formation technologies to build aninfOrmation channel, which realizes quick assembling and exploitingof global dispersed design resources, customers' participating indesigning process and team-based collaboration inside or amongenterprises, to run through customers and enterprises, both inside andoutside .All these form an individualized,innovative and rapidnetwork-based design mode,which helps enterprises to succeed in thecompetition in market. But at the same time during the process ofdelivering with these information how to insure the safety problem ofthose. Then main contents are listed as the following f1. On the basis of analyzing the possible change of organizationstructure, style of informatiol1 obtaining and designing activities, ageneral frame of network-based design is put fOrward. The major modeof network-based design is also studied and further more derive the safetyproblem of the design infOrmation during the process of delivering with theinformation.2.An insecure network environment results in network informationproblems during the network-base design. Therefore, on the basis ofstudies on infOrmation supporting frame of the network-baseddesigning, security technologies are discussed respectively inaccordance with the general request on information security .Thetechnology architecture of infOrmation security of the network-baseddesign is brought forward.3 .Cryptogram is the ker11el of infOrmation security .On the groundChengdu 2002.6of the general request on information security of information management system of the network-based design. The cryptogram-based security infrastructure of designing information management is brought forward.4. Analyzing the security problems of information access, information transfer and storage of designing information management system .The cryptogram-based information security of information access, information transfer and storage are put forward respectively.
