Summary:
As a countermeasure against cyberattacks, we have been studying a metabolic router. This route comprises multiple virtual routers redundantly. The current active virtual router is switched by a newly created one periodically. The after-use one is deleted. Here, the latent malware is also deleted together. However, malware may spread between redundant virtual routers. In order to solve this problem, this paper designs a router metabolism scheme where a redundant period is minimized. In this scheme, a newly created virtual router immediately switches itself with the active one. In addition, the after-use one is deleted as soon as possible. Those controls are achieved by means of combining a provisioning function of virtual routers with a switching function of them. Consequently, malware spreading within a hardware router can be suppressed.
