Abstract
"MéTODO PARA PROCESSAMENTO DE DADOS CODIFICADOS PARA UM PRIMEIRO DOMìNIO RECEBIDO EM UMA REDE PERTINENTE A UM SEGUNDO DOMìNIO". A invenção refere-se a um método para processar dados (LECM1), codificados por intermédio de um processo de codificação exclusivo a um primeiro domínio de tal modo que os referidos dados não possam ser decodificados diferente de por intermédio de um primeiro segredo (KN1) exclusivo do primeiro domínio. Os referidos dados são recebidos em um dispositivo de exibição (202) conectado a uma rede pertinente a um segundo domínio. O método compreende as seguintes etapas para o dispositivo de exibição de: (a) transmissão (404) de pelo menos uma parte (E{KN1}(KC)) dos referidos dados codificados para um dispositivo de processamento (211) conectado à rede; (b) recebimento (408) do referido dispositivo de processamento (211) de pelo menos um elemento (E{KN2}(K<39>C)/E{K<39>C}(KC)) para decodificar os referidos dados recebidos por intermédio de um segundo segredo (KN2) exclusivo do segundo domínio, o referido segundo segredo sendo mantido no dispositivo de exibição.
