Abstract
"MéTODO E SISTEMA PARA DISTRIBUIçãO SEGURA DE CONTEúDO ENTRE DISPOSITIVOS EM UMA REDE, E, DISPOSITIVO CENTRAL PARA ADMINISTRAR UMA REDE". A presente invenção relaciona-se a um método, um sistema e um dispositivo central para distribuição segura de conteúdo entre dispositivos em uma rede. A invenção é baseada na idéia que um domínio autorizado é estabelecido com um dispositivo central administrando a rede. Quando um dispositivo entra na rede, o dispositivo central registra o dispositivo que entra e emite pelo menos um certificado ao dispositivo que entra. O registro para assegurar que o dispositivo que entra seja um dispositivo autorizado, significando que um fabricante de dispositivo autorizado proveu o dispositivo. Devido à segurança de rede, dispositivos não autorizados não são aceitos na rede. O conteúdo é distribuído entre os dispositivos na rede baseado em autenticação por meio do pelo menos um certificado emitido para cada dispositivo. A distribuição de conteúdo de um primeiro dispositivo para um segundo dispositivo é habilitada pelo primeiro dispositivo autenticando o segundo dispositivo, por meio do pelo menos um certificado do segundo dispositivo e vice-versa.
