Abstract

"MéTODO E APARELHO PARA RESPECTIVAMENTE FORNECER E MANTER UMA DETERMINADA ASSOCIAçãO DE SEGURANçA DURANTE UMA TRANSFERêNCIA DO TERMINAL MóVEL". Uma associação de segurança existente é re-estabelecida quando um evento de transferência de comunicação ocorre em um sistema de comunicação de rádio, tal como o IEEE 082. 11 ou o HIPERLAN, onde a associação de segurança existente entre o terminal móvel e a rede de comunicação sem fio é mantida quando a transferência de comunicação ocorre dentro da rede. A autenticação durante o evento de transferência é alcançada pelo procedimento de desafio/resposta. De acordo com o procedimento de desafio/resposta cada membro de um par de comunicações, que é feito de um novo ponto de acesso e, o terminal móvel que está experimentando uma transferência para um novo ponto de acesso, envia o desafio para o outro membro do par de comunicações. Cada membro do par de comunicações então calcula a resposta para o seu desafio recebido, e estas respostas são enviadas de volta para o outro membro do par de comunicações. Cada membro do par de comunicações então compara a sua resposta recebida à resposta correta. Quando estas comparações estiverem corretas, a comunicação de carga útil começa entre o segundo ponto de acesso e o terminal móvel.
