The IP converge the multi-applications over Internet, and ATM will construct global networks for IP development. It is a significant research to associate those projects. The vision is that company or enterprise will have ATM switches on their own site to transfer bulk data across Internet. In this paper, we propose a lightweight security mechanism to support secure communications for ATM Networks. The mostly threats and attacks could be protected through authentication and confidentiality

The security policy will process uncontrollable state with default criteria. We utilize an embed-policy as conflict resolution to promote the reliability of lightweight security system.
