DEVICE FOR PROTECTING A MEMORY AGAINST FAULT-INJECTION ATTACKS

摘要

The invention relates to a memory (1) protected from fault injection during data readout. The memory includes means for reading reference data (WL(ref)) out of the memory during a step of reading out data stored in the memory; means (CTL) for comparing the read-out reference data with an expected value; and means (CTL) for generating a error signal (ER) when the read-out data differs from the expected value. The invention is useful for protecting smart card memories.
