Digital Right Management Research Based On Mobile Agent Technology

With the joint development of Internet and digital technology, more and more digital products have been taken on the big and open web, and then digital products have been got more extensive spread and application. Although people can share information, they also ignore that interests of much more people have been got to damage from the appearance of digital products to its widespread use. In these years, problems like whose right, legal use, legal rights and interests of digital products, had troubled all circles of people from different fields, for example, the owner of digital products, propagator of it and user too, then, some of people may edit, modify, copy and spread digital products at random, of course, the protection of digital products is to be of great urgency.This research use mobile agent technology and IBM Aglet system as theory base, move on with the actual situation, and use Java programming language, development toolkit Eclipse, Aglet 2.0.2 development platform to complete protecting digital products in some parts that other techniques are hard to finish it.This research makes use of One-Time Password to accomplish identity verification between user and server, it is to make sure of confidential user information, even person who intercept the password once, he still does not get the really password. It also use digital signature and RSA to complete two-way identity verification between user and provider of digital products when user use the products, that is sure of two sides are confidential. Practical and satisfying mobile agent has been established, it completes dispatching, retracting, communication of mobile agent. The way that together use of package of method and remote method invocation, accomplish verifying the digital right information in a remote port, and also got the using state of user, then make some effects of using about user. this application also use knowledge of JCE of SUN and SSL technology to make some research of mobile agent security and it security of communication, and finish it to some extent.It makes up of user identity verification, mobile agent research, mobile agent communication and mobile agent secure commutation parts. And it protects digital products by researching user login identity verification, using identity verification, mobile agent building, mobile agent allotment, mobile agent state reply, mobile agent mobility, mobile agent listener of using, mobile agent security and mobile agent communication .etc.This research does not only face to digital right management and explore it, and mobile agent techniques are led into it,to some extent, it brings up a new train of thought and opinion for digital right management.
