Method for processing encrypted data for the first region which is received by the network belonging to the second region

摘要

Being the method of being designed in such a way that it is received the presentation device where as for this invention, following to the encoding method of specification the data which is encoded (LECM1) being the method of processing in the 1st territory, as for the data 1st secret of specification (K _N1) help dying it is not possible in the aforementioned 1st territory, the aforementioned data, belongs to the 2nd territory and is connected to network to be decoded, (202) in, because of the presentation device:(A) at least portion of the aforementioned encoding data (E {K _N1} (K _C))The processor which is connected to network (211) the stage which is transmitted (404); And(B) 2nd secret of specification (K _N2) with help in the aforementioned 3rd territory, the description above at least one which is used in order to decode the data which is received element (E {K _N2} (K'C)|E {K'C} (K _C))The aforementioned processor (211) from being the stage which is received, the aforementioned 2nd secret is included in the presentation device, stage (408);It possesses, it regards method.
