Abstract

<B>MéTODO PARA GARANTIR COMUNICAçãO ATRAVéS-DO-AR EM UM SISTEMA SEM FIO<D> No método para garantir de forma segura comunicação através-do-ar em um sistema sem fio, um usuário móvel envia uma solicitação de acesso ao sistema e dados fictícios associados com a solicitação de acesso ao sistema para uma rede. A rede envia uma primeira seq³ência de dados incluindo uma primeira porção de dados para o usuário móvel em resposta à solicitação de acesso ao sistema e aos dados fictícios. O usuário móvel extrai uma primeira porção de dados a partir da primeira seq³ência de bits, e envia uma segunda seq³ência de bits para a rede. A segunda seq³ência de bits inclui uma segunda porção da dados. Tanto o usuário móvel como a rede geram um código baseado na primeira porção de dados e na segunda porção de dados, e estabelecem um primeiro canal de comunicação criptografado e autenticado em cooperação usando o código. O usuário móvel então transfere a informação de autorização para a rede através do primeiro canal de comunicação criptografado e autenticado. Se aceita, um segundo canal de comunicação criptografado e autenticado é estabelecido. A rede então envia informação sensível tal como código-A ou de raiz para o usuário móvel através do segundo canal de comunicação criptografado e autenticado.
