Abstract

"PAREAMENTO DE MóDULO DE SEGURANçA PORTáTIL". Um método de pareamento de um primeiro elemento e de um segundo elemento, em que o primeiro elemento e o segundo elemento forma um primeiro sistema de decodificação entre uma pluralidade de sistemas de decodificação receptores em uma rede de radiodifusão. Cada sistema de decodificação receptor é adaptado para desembaralhar a informação audiovisual embaralhada recebida através da rede de radiodifusão. Uma primeira chave única na rede de radiodifusão é selecionada. Uma segunda chave é determinada de acordo com a primeira chave, tal que uma combinação da primeira chave e da segunda chave habilita descriptografar dados de controle criptografados difundidos que são recebidos para serem descriptografados por cada sistema de decodificação receptor, os dados de controle criptografados sendo idênticos para cada sistema de decodificação receptor. A primeira chave e a segunda chave são atribuídas, respectivamente, ao primeiro e ao segundo elemento.
