Computer-readable medium provided with a memory area ( 2; 26, 28 ) for storing data and a distinct microprocessor ( 3 ) having a communication interface ( 4 ), a memory unit ( 7 ) and a processor unit ( 5 ) connected to both the communication interface ( 4 ) and the memory unit ( 7 ). The data may include a first data portion which is arranged to be read and decrypted by a computer arrangement ( 11 ) provided at least one condition is met, and the microprocessor ( 3 ) being arranged to generate at least one cryptographic key once the condition is met that is necessary to decrypt the data. The invention is also directed to a computer arrangement arranged to communicate with such a medium. |
