Security mechanisms for mobile code in evolutionary networks

Considering that evolutionary networks with dynamic program loading structures introduces potential security problems, some security mechanisms for the mobile code in this kind of networks were proposed. Because the mobile code is in the form of data when in transmission while in the form of program when in execution, the research addressed both the security of static data and the security of dynamic program. A mechanism for verifying the integrity of the mobile code was proposed to ensure the safe transmitting and deploying of the mobile code. The trust platform module was used to generate the encryption key and to verify the hardware and software configurations of the node. The runtime dynamic access control mechanism and the resource monitor management mechanism were proposed to guarantee the mobile code's safe execution. These mechanisms improve the security of evolutionary networks.
