Abstract

"SISTEMA DE ACESSO CONDICIONAL PARA CONVERSORES SET-TOP-BOX" Um sistema condicionalmente estabelece um canal de comunicação entre dois dispositivos somente se um dispositivo é autenticado pelo outro dispositivo. A autenticação do segundo dispositivo pelo primeiro dispositivo envolve enviar uma mensagem para o segundo dispositivo; receber, do segundo dispositivo, a mensagem criptografada usando uma chave privada do segundo dispositivo e um certificado digital tendo uma chave pública do segundo dispositivo; descriptografar o certificado digital para obter a chave pública, usar a chave pública para decriptografar a mensagem e comparar a mensagem decriptografada com a mensagem originalmente enviada para o segundo dispositivo.
