Implementation of light-weight IKE protocol for IPsec VPN within router

IPsec protocol has been widely deployed at remote business environment because of its properties, confidentiality and integrity for network traffic. Before using IPsec protocol, it is needed that negotiations of security associations and keys between two end points of IPsec tunnel. IKE protocol is used when negotiation is done automatically. This paper introduces the light-weight IKE protocol that can be applied to an embedded system such as router. We prove that this IKE protocol has been implemented based on RFC by working with the other commercial IKE protocol and show the negotiation performance of IKE protocol by using test tool
