Abstract

Система для создания цифровых данных содержимого, доступных оконечному устройству пользователя (26.1), содержащая исходную точку (12) для создания зашифрованных исходных данных, содержащих данные содержимого, зашифрованные ключом (15) из пары ключей шифрования содержимого (CEK), и совместно используемые данные, относящиеся к CEK. Совместно используемые данные зашифрованы первым ключом второй пары ключей шифрования, и эта вторая пара ключей связана с целевым промежуточным устройством 18.1. Промежуточное устройство 18.1 содержит процессор 22.1 для приема зашифрованных исходных данных. Процессор на промежуточном устройстве выполнен с возможностью взаимодействия с портативным переносным устройством хранения (PSD), которое связано с оконечным устройством пользователя 26.1. Оконечное устройство пользователя связано с третьей парой ключей шифрования. Процессор 22.1 выполнен с возможностью создания зашифрованных промежуточным устройством данных путем расшифровки зашифрованных совместно используемых данных, используя ключ второй пары ключей, и шифровки полученных расшифрованных данных, используя ключ третьей пары ключей. Процессор воссоздания CEK выполнен с возможностью использования алгоритма и входных совместно используемых данных для воссоздания CEK. Расшифровывающий процессор выполнен с возможностью использования воссозданного CEK для расшифровки зашифрованных данных содержимого.
