Abstract

Un método para procesar paquetes con datos codificados recibidos mediante un cliente a partir de un servidor a través de al menos una red en donde los paquetes de datos comprenden al menos un encabezamiento de codificacion y un campo de informacion, extrayendo el encabezamiento de codificacion a partir de un paquete de datos, extrayendo y decodificando el campo de informacion codificado para formar datos libres, generado un segmento de paquete de datos libres, la transmision segura a base de paquetes de datos de contenido a partir de un servidor hacia al menos un cliente comprende recuperar un paquete de datos libres que comprende un campo de informacion no codificado, dividir el campo de informacion no codificado en uno o más segmentos, aplicar un algoritmo codificado para cada segmento para generar segmentos codificados, generar encabezamiento de codificacion para cada segmento codificado que comprende un paquete con datos codificados para cada segmento codificado que comprende el encabezamiento codificado, un paquete de datos del encabezamiento y la transmision de cada uno de los paquetes compuestos al cliente.
