Abstract
A method and a circuit for checking the coherence between data read from a first area of a memory of a microcontroller and the address of these data, including calculating a current digital signature of the read data by a function also taking into account the address of these data in the memory, and checking the coherence between the current signature and a previously-recorded signature.
