Title: METHOD FOR SECURELY PROVIDING STORED INFORMATION IN AN ELECTRONIC COMPONENT
Abstract:
Method for securely providing stored information in an electronic component (10) having a nonvolatile data memory (11), having the following steps: – reading at least two data structures (200) from the nonvolatile data memory (11), – performing a respective error check (100) for each of the data structures (200), so that a respective data correctness of the respective data structure (200) is confirmed, – ascertaining at least one respective version feature (220) from each of the data structures (200), – performing a version check (110) for the data structures (200) on the basis of the ascertained version features (220), so that a defined version dependency between the data structures (200) is confirmed, – ascertaining a respective piece of useful data information (210) from each of the data structures (200), – performing a redundancy check (120) for the data structures (200), so that a match for the ascertained useful data information (210) of the data structures (200) is confirmed, – providing at least one of the pieces of matching useful data information (210) on the basis of the error check (100) and the version check (110) and the redundancy check (120).
