Over P2p-based Mobile Agent E-commerce Model And Its Security

With the grown-up of Internet and the technology of information, the scale of Net is becoming more and more large, more and more people begin using Internet. The technology of information is applied to traditional commerce field. That is e-commerce. It makes market globally, commerce trivially and consumption individually. It has a far-reaching effect upon the world economy. Now the most e-commerce scheme and application system are based on the frame of Browse/Server. But its static characteristic isn' t satisfied with the request of e-commerce. Then it is important to find an effective scheme for e-commerce especially.In recent years, a new distributed model has been inducted in e-commerce field. That is Mobile Agent. Mobile Agent is a segment of executable program. It can carry its code and state from one node to another node in net. Then it searches appropriate resource in order to perform its task. It provides a new kind of calculating pattern. It compares with traditional distributed technology (for example, Client /Server, Code-on-command, etc). It has lots of adjustability and advantages in large distributed system. E-commerce involves many computer fields. It includes not only the process of collecting information from stores, but also the processes of goods preparation among or within stores, security guarantee, payment mechanism and storage management. Now there are many applications based on mobile agent, but there isn' t any killer application for resolving the goods preparation within store.This paper applies mobile agent in e-commerce field. It combines with the research of the project, which is undertaken by Shandong Province science and technology department and which emphasizes the security of business data when it transfers on Internet. This paper aims at the problem of goods preparation within store in e-commerce system. It designs a model toresolve the problem of goods preparation for a large chain store. It combines mobile agent with p2p and put chord arithmetic in use, which is the representative Router arithmetic in p2p net. When it searches goods information it only appoint the practical information id but not physical address. So it expedites the search. At the same time, in order to ensure the stores' intent, the integrality and privacy of goods forms, avoid malicious attack between mobile agent and agent platform and especially prevent malicious agent or third-party from filching the goods forms carried by agent, the paper applies a secret hash digital signature arithmetic to the model. It not only has a rapid speed but also makes file and signature carried and saved apart. In addition, it reduces the request of storage room and realizes the security authentication between mobile agent and agent platform. In the end, this paper sums up the past work and puts forward prospect for the future.
