Abstract
MÉTODO E SISTEMA PARA PROCESSAMENTO SEGURO DE MATERIAL CHAVE DE AUTENTICAÇÃO EM UMA REDE SEM FIO AD HOC Um método e um sistema para processamento seguro de um material de chave de encriptação em uma rede sem fio ad hoc permitem uma distribuição segura do material de chave de autenticação entre um autenticador de malha (110) e um distribuidor de chave de manha(115), os quais podem estar separados por múltiplos enlaces sem fio. O método inclui a derivação de uma chave transiente formada em pares para distribuição de chave (PTK - KD) usando-se um elemento de informação de segurança de mantenedor de chave de malha (MKHSIE). Uma chave mestra formada em pares de autenticador de malha (PMK - MA) então é requisitada usando-se um primeiro elemento de informação de chave encriptada de malha (MEKIE) então é desencriptado para a obtenção de chave mestra formada em pares de autenticador de malha (PMK - MA).
