暗号化されたユーザデータオブジェクトの伝送方法
Document Type and Number:
Japanese Patent JP2005536780
Kind Code:
A
Abstract:
The present invention relates to a method for handling or transmitting encrypted user data objects. According to such method, a data preparation component (D) of a data preparation system provides user data objects. The data preparation component first encrypts a user data object that has been prepared. It then determines a checksum of the encrypted user data object and creates a container data object (DCF), in which the encrypted user data object and the determined checksum are provided. The container data object is subsequently transmitted to a first telecommunications device (A). Preferably, in order to use the encrypted user data object, the data preparation component (D) transmits descriptive information (BI1) containing a description of the possible usage rights for the encrypted user data object to the telecommunications device (A). After the selection of a specific rights object (RO), the data preparation device first transmits a confirmation object (DCFV) to the telecommunication device in order to verify the compatibility of the desired rights object and the encrypted user data object provided in the telecommunication device and if said verification is successful, subsequently transmits the rights object (RO) to the telecommunications device (A).
