Abstract

sistema e métodos para gerenciamento de chave para sistemas de comunicação sem fio. uma abordagem de gerencialmento de chave nova é fornecida para tronar segura handoffs de comunicação entre um terminal de acesso (118) e dois pontos de acesso (110, 112). esta abordagem fornece para efetuar handoff de forma segura comunicações entre um terminal de acesso e ponto de acesso sem arriscar exposição de uma chave mestra para o terminal de acesso. chaves temporárias (i-mk) são derivadas para handoffs de baixa latência e autenticação segura entre um novo ponto de acesso (112) e o terminal de acesso. em um aspecto, um esquema de gerenciamento de chave distributivo é fornecido no qual um ponto de acesso atual (110) gera nova chave de segurança (com base em uma chave mestra de segurança associada com o terminal de acesso) a pontos de acesso.
