Sobre IBD

As redes móveis assumem um papel cada vez mais importante no domínio das comunicações sem fios. Estas redes apresentam características interessantes (conforto proporcionado pela mobilidade, acesso ubíquo à informação, etc.), mas, infelizmente, têm recursos limitados (energéticos, de processamento, etc.). O facto de as redes móveis oferecerem serviços, muitas vezes, muito sensíveis, torna a noção de segurança primordial e indispensável. No entanto, devido à limitação de recursos, o desenvolvimento de mecanismos de segurança é um desafio a ser enfrentado. No âmbito deste trabalho, pretendemos propor um protocolo de autenticação dedicado às redes móveis, baseado na troca de chaves, tendo em conta as restrições associadas a estas redes (mobilidade, utilização económica de energia, etc.). O objetivo é autenticar os nós da rede e distinguir os nós intrusos utilizando como mecanismo a criptografia elíptica.
