Research On Trusted Port Scan Mobile Agent

The rapid development of the network technology to a large extent changed the way of the people live and production.People enjoy the convenience of the technology advances,while the security of computer networks also placed in front of us.To some extent,computer networks need the system to ensure their authenticity,integrity,confidentiality,effectiveness and rejection and so on.At present,the existence security way of computer networks only increased number of security levels between computer and the outside of the network,such as passwords and encryption,etc.All of these methods are passive program,and the basis of these security levels,such as the operation system and the hardware itself may be exist the fatal flaws.It has proved that this idea can only solve the problem partly and temporary,and the extent of the problem-solving not be satisfactory.Therefore,Trusted Computing Group proposed the concept of Trusted Computing.Trusted Computing is a new computing platform,its software and hardware have made the appropriate provisions,the objective of the trusted computing is to establish a comprehensive verification system in the computer system,then to improve the security of the entire computer system.Trusted Computing uses a technology that combination hardware and software,introduced a trusted hardware device in the platform as a trusted root.Then establish a trusted chain,the trust can extend to the above level.Finally,the trusted relationship of the chain extendend to the entire computer system,to ensure the credibility of the computer system.Based on the trusted platform ,the mobile agent which attractive by people may get very good display.In the trusted enviroment,we can loaded aglet platform,assume that the aglet platform is trusted too.In the trusted aglet platform,we can design a trusted port scan mobile agent.The mobile agent is send to the target host to scan the port.After the mobile agent scan the port,the result of the port information can return to the local host.This paper advanced the architecture of trusted port scan mobile agent,use the frame chart descript it and use writing analysis the detail.Then,we construct the trusted experiment platform on Linux.We using the existence open source project TPM Emulator to simulated the trusted platform module. In trusted software stack layer,we also use open source project IAIK jTSS.At last,load aglet based on the build experimental platform.Because the platform is trusted,so suppose the loaded aglet platform is also trusted.The trusted aglet platform generate a port scan of mobile agent,the mobile agent is send to the target host to scan the port information,then the information of the port of target is return to the local host.
