摘要
Countermeasures against fault injection attacks of a cryptographic integrated circuit, and more specifically laser fault injection attacks are provided. The invention consists in generating sequences of bits belonging to a set of allowed sequences, and storing these sequences on a set of Flip-Flops. Then the sequences stored on the Flip-Flops are checked and, if they do not belong to the allowed sequence, this is the sign that a fault injection attack occurred and caused a bit flip in one of the flip-flops. An alarm signal is then generated.
