Abstract
"AUTENTICAçãO DE PONTE DE INFORMAçõES DE DOWNLOAD EM UM SISTEMA DE ACESSO CONDICIONAL". Um sistema de televisão a cabo provê acesso condicional a serviços. o sistema de televisão a cabo inclui um extremo de cabeça do qual "instâncias" de serviço, ou programas, são difundidos e uma pluralidade de unidades set top para receber as instâncias e seletivamente decriptografar as instâncias para exibição para assinantes do sistema. As instâncias de serviço são criptografadas utilizando chaves pública e/ou privada fornecidas pelos provedores de serviço ou agentes de autorização central. As chaves utilizadas pelos set tops para decriptografia seletiva também podem ser de natureza pública ou privada, e tais chaves podem ser reatribuídas em tempos diferentes para fornecer um sistema de televisão a cabo no qual as preocupações com pirataria são minimizadas.
