Method and arrangement for protecting information

An arrangement for protecting data saved in a memory, the arrangement comprising:

• at least one memory element and at least one data processing element combined by means of required interfaces into a data processing entity;
• and
• at least one scrambler connected to the data processing entity, and configured to scramble a form in which the data to be saved in the memory element is represented or configured to descramble data saved in the memory element into plain text when data is taken from the memory element for the use of the data processing elements, and where data to be saved in different areas of the memory element is protected in different ways and the division of the memory element is implemented by using a configuration register.

An arrangement for protecting data saved in a memory, the arrangement is configured to:

• combine at least one memory element and at least one data processing element by means of required interfaces into a dato processng entity;
• scramble connected to the data processing entity, wherein the scrambler is configured to scramble a form in which the data to be saved in the memory element is represented and
• descramble data saved in the memory element into plain text when data is taken from the memory element for the use of the data processing elements, wherein data to be saved in different areas of the memory element is protected in different ways and the division of the memory element is implemented by using a configuration register.
