Abstract:

Friendly Worrn-Anti-Worm（W-A-W） is a new active worm countermeasure, but the state of the anti-worm used in W-A-W can not be controlled and frequent ly brings heavy traffic itself. To solve these problems, we propose the concept of controllable worm. The definition, distributed framework and work flo  w of the controllable worm are presented. Then we use the controllable worm to fight worms and propose a ＂Controllable Worm-Anti-Worm＂ model （CW-A-W   ）. We analyze the propagation model of CW-A-W, and prove that the controllable worm has the merits of low traffic and controllable state,and can reduce     e the complexity of the W-A-W model.

Key words: worrn-anti-worm controllable worm propagation model
