Abstract

Los métodos, sistemas y medios legibles por computadora pueden facilitar el cifrado de un identificador de dispositivo utilizando una propiedad de identificación de un SoC. Un identificador único de un cablemódem puede cifrarse utilizando una clave única u otra propiedad única de un SoC asociado con el cablemódem. Cuando se inicia un proceso de autenticación en el cablemódem, el identificador único cifrado del cablemódem puede descifrarse utilizando la clave única u otra propiedad única del SoC, produciendo así el identificador único del cablemódem. El identificador único descifrado del cablemódem puede enviarse desde el cablemódem a un controlador aguas arriba durante el proceso de autenticación. En modalidades, una clave de ofuscación puede usarse para cifrar y descifrar el identificador único del cablemódem, y la clave de ofuscación puede generarse utilizando un identificador único del SoC.
