Mobile Agent Data Security Protection

With the rapid development of Internet and Network,A new distributed network computation pattern based on mobile agent technology is becoming heavy investigation.It is considered the key technology of the new age distributed computation following the CORBA and EJB.It has mobility,autonomy and some other strong points.Mobile agent technology can effectively improve the application of network, reduce the flux of network and improve the utility of resources in network.It has greate potential power in its application.This paper,firstly introduces the mobile agent technology,then emphatically studies the security problems of mobile agent and does some analyse and comparison among the existent security mechanism.Then,we deeply and systematically study the mobile agentplatform-----IBM Aglet.Lastly, combine with the application development method ofAglet,we design a distributed information gathering system based on mobile agent,ar,d use the encryption technology to protect the data belonged to the mobile agent. This system has highly efficiency searching,sustains interruptedly computation and has high network adaptability.
