Abstract

"ARQUITETURA DE DIFUSãO DE DADOS BASEADA EM PACOTE SEGURO". A presente invenção refere-se a um método para processar pacotes com dados criptografados recebidos por um cliente de um servidor através de pelo menos uma rede em que os pacotes de dados compreendem pelo menos um registro de início de criptografação (46) e carga útil (45), extrair o registro de início de criptografação (54, 55; 69) de um pacote de dados, extrair e descriptografar a carga útil criptografada para formar um dado claro, gerar um segmento de pacote de dados claros. A transmissão baseada em pacote seguro de dados de conteúdo a partir de um servidor para pelo menos um cliente compreende recuperar um pacote de dados claros compreendendo uma carga útil não criptografada, dividir a carga útil não criptografada em um ou mais segmentos, aplicar um algoritmo criptografado a cada segmento para gerar segmentos criptografados (47), gerar registro de início de criptografação para cada segmento criptografado, compondo um pacote com dados criptografados para cada segmento criptografado compreendendo o registro de início criptografado (46), um registro de início de pacote de dados e transmissão de cada um dos pacotes compostos para o cliente.
