Abstract

"MéTODO E SISTEMA PARA ASSEGURAR UMA TRANSMISSãO DE DADOS SEGURA ENTRE O PRIMEIRO E O SEGUNDO DISPOSITIVOS DE COMUNICAçãO EM UMA COMUNICAçãO SEM FIO DE ALCANCE LIMITADO, E, DISPOSITIVO DE COMUNICAçãO". A invenção descreve um método para assegurar uma transmissão de dados segura entre o primeiro (2) e o segundo dispositivo de comunicação (3) em uma comunicação sem fio de alcance-limitado. Para estabelecer uma conexão de transmissão de dados segura, os dispositivos de comunicação (2, 3) conduzem a um estágio de troca da chave para gerar ao menos uma chave compartilhada (CH) entre os dispositivos de comunicação. Após o estágio de troca da chave, ao menos a primeira (C1) e a segunda (C2) cadeias de caracteres de verificação são formadas, as cadeias de caracteres sendo baseadas ao menos em uma cadeia de caracteres randómicos única e nas chaves (CH1, CH2) geradas em cada dispositivo de comunicação no estágio de troca da chave. Assim, a segurança da conexão que é estabelecida é assegurada ao comparar a correspondência das cadeias de caracteres de verificação (C1, C2). A invenção também descreve um sistema de comunicação e um dispositivo de comunicação, no qual o método será aplicado.
