Abstract

"SISTEMA, MéTODO E DISPOSITIVOS PARA AUTENTICAçãO EM UMA REDE DE áREA LOCAL SEM FIO (WLAN)". Um sistema (100) para autenticação em uma rede de área local sem fio (WLAN) inclui um centro de autenticação CDMA2000 (190) para autenticar credenciais CDMA2000 (110), um servidor de autenticação WLAN (150) para utilizar as credenciais CDMA2000 para autenticar dispositivos WLAN que detêm credenciais CDMA2000, e pelo menos um dispositivo WLAN (130) que detém credenciais CDMA2000. O servidor WLAN (150) efetua um desafio e uma resposta global CDMA2000 (213) e um desafio e uma resposta singular CDMA2000 (223) com o dispositivo WLAN para obter uma chave de criptografia CDMA2000 (233). O servidor WLAN (150) deriva uma chave mestra da chave de criptografia CDMA2000 (234) e utiliza a chave mestra para efetuar um desafio e uma resposta WLAN (237) com o dispositivo WLAN (130) e então deriva chaves de sessão da chave mestra (240). As chaves de sessão protegem a comunicação entre o ponto de acesso WLAN (140) e o dispositivo WLAN (130).
