Abstract

In one embodiment of the present invention, there is disclosed a reversible method of processing data comprising the data being encrypted before being written to a non-volatile memory wherein the data cannot be accessed without decryption in the case of a direct physical access to the non-volatile memory.

Claims

1. A method of processing data before being written or stored in non-volatile comprising:

Encrypting the data before the data being written to non-volatile memory wherein the data cannot be accessed without decryption in the case of a direct physical access to the non-volatile memory wherein the encryption of data is carried out by an encryption process which comprises the user data and associate header data undergoing at least one of the two steps of scrambling and encoding.
