PROCEDE DE DETECTION D'ANOMALIES DANS UN CIRCUIT DE CRYPTOGRAPHIE PROTEGE PAR LOGIQUE DIFFERENTIELLE ET CIRCUIT METTANT EN OEUVRE UN TEL PROCEDE |
摘要 |
<p>In a method for detecting anomalies in a circuit protected by differential logic and which processes logic variables represented by a pair of components, a first network of cells carrying out logic functions on the first component of said pairs, a second network of dual cells operating in complementary logic on the second component, the logic functions being carried out by each pair of cells in a pre-charge phase placing the variables in a known state on input to the cells and followed by an evaluation phase where a calculation is performed by the cells, the method includes detecting an anomaly by at least one non-consistent state.</p> |
