Mobile Agent-based Information Collection System And Security Research

With the great increasing of informations and business over Internet and thechanging of supply, the enviroment become more and more complex.People are longingfor a new frame of E-business that can make them get services and exchangeinformations in Internet by quickly accessing it anywhere and anytime.They also hopethat the frame can compare the products and services through the whole world's supplychain by resources-filtering,information-reforming,analyse-optimizing andflow-serching.The appearing of Agent technology and Java language make people'dreamcome true.Mobile technology is a new kind of technology of distributed computation,it ownsadvantages of mobility and autonomy.It is considered the key technology of the new agedistributed computation following the CORBA and EJB.Mobile agent technology caneffectively improve the application of newwork,reduce the flux of network and improvethe utility of resources in network.It has great potential power in its application.There are few successful applications with mobile agent in the mobile agentresearch and application fields.The study to agent technology is mostly at the theoreticaland mathematical phase and few mature system based on mobile agent existed.Peoplestill has doubt to safety of the existed immature system.If we can not solve thoseproblems,which will seriously hinder the application of mobile agent thechonoly.The main purpose of the thesis is to explore the concrete application of mobile agenttechnology in Internet enviroment.Adopt the mobile agent techonoly to study anddevelop a distributed information collecting system based on mobile agent,and use theencryption technology to protect the data belonged to the mobile agent.We also study andanalyze the mechanism of systematic safety in detail.All researchs and the design worksembody in the information system in Internet environment based on the mobile agentwhich is realized by us.
