Abstract
The invention relates to a device for decrypting protected content and for providing the decrypted content for playback. The device comprises one or more system software modules providing functions for facilitating the decryption of the protected content and at least one client software module assigned to a provider of protected content. The client software module is adapted to access functions of the system software modules in order to control the system software to decrypt the protected content of the provider. Moreover, the device is adapted to validate the system software and/or a further client software module and to prevent the decryption and/or provision of the protected content of the provider, if the system software and/or the further client software module are not validated successfully. The validation of the system software and/or a further client software module comprises a comparison of identification data of software modules of the system software and/or further client software modules loaded in a processor of the device and identification data included in a revocation list assigned to the provider. In addition to the device, the invention relates to a method for operating the device.
