Método e analise de desempenho e segurança de uma rede IPv6 utilizando IPsec em modo túnel

Abstract

This work has the focus on the Internet Protocol version 6 (IPv6), specifically on the use of tunnel mode in Internet Protocol Security (IPsec) for IPv6, deploying a network of computers. The focus of this project was the evaluation, as well as the method, of performance and security of the network. The project aimed to create a topology with two local networks, one called as matriz and another as filial, using IPsec tunnel mode to communicate. The use of IPsec in tunnel mode forms a private connection between the two border routers that are on each side of this communication. The problem is, from a completely IPv6 network, evaluating the performance and security of the network, thus to ensure the authenticity and integrity characteristics of network packet, as well as data confidentiality, it is necessary to use specific headers of IPsec. Headers analyzed in this work were: Autentication Header (AH) and Encapsulating Security Payload Header (ESP). The results showed that the IPsec with AH and ESP headers are recommended to be used because the performance difference compared to not using IPsec get stabilized on 7 % (with 7 routers) and 9% (with 3 routers), according to the experiments.
