Abstract

"DISPOSITIVO E PROCESSO PARA ASSOCIAçãO DE REDE LOCAL SEM FIOS E PRODUTOS CORRESPONDENTES". A presente invenção diz respeito ao dispositivo de associação de WLAN (5) e processo para associar uma estação nova (3) a uma WLAN (1) , por meio de um aparelho central (2). O dispositivo de associação compreende dispositivos de recepção (11) e envio (12) para trocar sinais entre a estação e o aparelho central, dispositivos de segurança (13) para automaticamente fornecer ao aparelho central pelo menos uma chave secreta central (K), e dispositivos de registro (14) para registrar a estação como parte da WLAN, sob permutas sem fios entre a estação e o aparelho central iniciadas por uma solicitação de associação enviada pela estação e protegida por meio da chave central e uma chave secreta da estação (K<39>) correspondendo à chave central. Os dispositivos de registro confirmam o registro da estação apenas quando o usuário executar uma ação de confirmação física (ACTION<39>) no aparelho central.
