Abstract

Patente de Invenção: <B>"SISTEMA DE COMUNICAçãO CONTROLADOR DE ACESSO DE DADOS DE DIFUSãO"<D>. é revelado um método e aparelho para permitir a uma estação receptora autorizada decriptar informação encriptada difundida por uma estação transmissora e para decriptar a informação dentro da estação receptora autorizada. O método inclui as etapas de armazenar um valor de Chave de Subscrição predeterminado na estação receptora autorizada e utilizar o valor de Chave de Subscrição predeterminado, gerando um valor de Chave de Decriptação. Em uma próxima etapa, a estação transmissora difunde um sinal que inclui a informação encriptada. Após o sinal difundido ser recebido na estação receptora autorizada, a estação receptora autorizada executa um algoritmo predefinido. O algoritmo predefinido utiliza o valor de Chave de Decriptação gerado para decriptar a informação encriptada do sinal recebido.
