METHOD FOR ENCRYPTING, STORAGE SYSTEM FOR A VEHICLE, MOTOR VEHICLE WITH A STORAGE SYSTEM AND COMPUTER-READABLE STORAGE MEDIUM

摘要

The invention relates to a method for encrypting first data (20) in a first memory (75) and for recording the encrypted first data (25) in a non-volatile memory (80), comprising the following steps: encrypting the first data (20) in the first memory (75) by means of a current encryption algorithm or by means of a block encryption algorithm, said block encryption algorithm being used to generate a current encryption in the counter mode; comparing the encrypted first data (25) in the first memory (75) to encrypted second data (35) in the non-volatile second memory (80) and determining the part of the encrypted first data (25) which is not identical to the encrypted second data (35); and finally recording the determined part (27) of the encrypted first data (25) from the first memory (75) in the non-volatile second memory (80) which is not identical to the encrypted second data (35).
