A Cooperative Authentication of IPSec and SEND Mechanisms in IPv6 Environments

The IPv6 network protects the IP layer by using the IPSec protocol and the SEND mechanism. However each host should be authenticated repeatedly when the two mechanisms are used at the same time. In this paper, we propose a cooperation scheme to share the authentication information between the SEND mechanism and the IPSec protocol. By sharing the authentication data of the host with the SEND mechanism, IPSec protocol expects the cost reduction for establishing a secure communication channel. We also evaluate the performance of the proposed mechanism by implementing the cooperation scheme.
