Abstract

"MéTODO E SISTEMA PARA TRANSFERIR DE MODO SEGURO UM CONJUNTO DE DADOS EM UM SISTEMA DE TELECOMUNICAçõES". Em um sistema de telecomunicações, dados que possuem sensibilidade maior e dados que possuem sensibilidade menor são identificados dentro de um conjunto de dados. Os dados que possuem sensibilidade maior são criptografados para produzir dados sensíveis criptografados. Em seguida, os dados que possuem sensibilidade menor e os dados sensíveis críptografados são criptografados para produzir um conjunto de dados criptografados. O conjunto de dados criptografados é em seguida transferido de uma unidade transmissora para uma unidade receptora. Informações sobre decriptografia podem ser anexadas aos dados sensíveis criptografados antes dos dados que possuem sensibilidade menor e os dados sensíveis criptografados serem criptografados para produzir um conjunto de dados criptografados. As informações sobre decriptografia podem incluir um identificador de algoritmo, um identificador de tecla e instruções de resposta de receptor. Na unidade receptora, o conjunto de dados é decriptografado para recuperar os dados que possuem menor sensibilidade. Uma segunda decriptografia das informações sensitivas criptografadas recupera os dados que possuem sensibilidade maior. Podem ser utilizadas informações sobre decriptografia anexadas para localizar e decriptografar as informações sensitivas criptografadas.
