Abstract

The invention relates to a device (DEV) and a corresponding method of using encrypted data (DATenc) stored in a first memory (MEM1) of said device (DEV), which device (DEV) additionally includes a more tamper-resistant second memory (MEM2). Encrypted data (DATenc) is read from the first memory (MEM1), encrypted data (DATenc) is decrypted with an associated key (K), and decrypted data (DAT) is stored in the second memory (MEM2). Hence encrypted data (DATenc) stored on said device (DEV) can be used in decrypted format without permitting the owner of the device (DEV) to access said decrypted data (DAT). One application is the emulation of a multitude of smart card applications by a mobile device.
