Protection of data in a memory associated with a microprocessor |
摘要 |
<p>The method involves calculating a current digital signature of read data with the help of a function taking into account an address (A) of the data in a memory. Coherence between the current signature and a signature previously recorded is verified. The recorded signature is stored in a zone of the memory at the same address as the data. Four groups of temporary storage registers are used for storing the data, the address, the signature extracted from the memory and the current signature.</p> |
