Abstract
In a method of storing data in a memory device, which data comprise content to be processed in a processing device in which the memory device is installed, the method comprises the steps of writing encrypted content (Enc_Krand(flash_content) into the memory device before installing the memory device in the processing device, wherein the content was encrypted by use of a first key (Krand), and accessing the first key (Krand) and encrypting the first key (Krand) by the aid of a second key (KIC; Ke) that is dependent on the processing device after installation of the memory device in the processing device, and writing the encrypted first key (EncSym_KIC(Krand); EncAsym_Ke(Krand)) into the memory device.
