A study of end-to-end VPN using IPv6 IPsec with online query

摘要

IPv6 (IP version 6) Internet has been stepping toward practical stage. It is very important for promotion of IPv6 Internet to develop new applications or services using end-to-end bi-directional communication, which is characteristic for IPv6. So, we propose flexible End-to-End VPN (Virtual Private Network) combination with IPSec (IP security) which is mandatory for IPv6 implementation conformance and PKI (Public Key Infrastructure) based on certificate. For the purpose of authentication, there are two methods to acquire the status of certificate, periodic query and online query. Online query is efficient to authenticate each other in real-time than periodic query. In this paper, we implement experimental IPv6 ad-hoc VPN system with online query, and evaluate round trip time per transaction and throughput with different rate of the frequency of online query.
