Abstract

"ATUALIZAçõES DE CHAVE EM UM SISTEMA SEM FIO MóVEL". A presente invenção descreve um esquema de atualização de chave de segurança para utilização em uma rede IP móvel. O esquema de atualização pode implementado para facilitar atualizações de chave de segurança entre um dispositivo móvel e um computador servidor que autentica o dispositivo móvel. As técnicas descritas aqui podem facilitar atualizações de chave de segurança de uma maneira que dá conta da perda potencial de mensagens durante a rotina de atualização, ou de outros problemas tipicamente encontrados em um ambiente de rede móvel. Desta maneira, as técnicas podem proporcionar um esquema robusto para atualizações de chave de segurança e pode aperfeiçoar a segurança da rede.
