A new dynamic address solution for moving target defense

The dynamic address techniques that dynamically change network properties including protocols and addresses have been a major focus area of moving target defense. Current dynamic address proposals have a common limitation that the changing scope of a certain terminal host is limited to its corresponding subnet in the process of address dynamically changing. A new dynamic address solution is proposed based on software defined network to enlarge the changing scopes of terminal hosts. The effectiveness of proposed solution is evaluated by an experimental network created by mininet. The experiment results show that the proposed solution could effectively manage the dynamically changing process and extend the terminal hosts' changing scopes to a great extent.
