PROCEDES DE CONTRE-MESURE DANS UN COMPOSANT ELECTRONIQUE METTANT EN OEUVRE UN ALGORITHME DE CRYPTOGRAPHIE A CLE PUBLIQUE DE TYPE COURBE ELLIPTIQUE DE KOBLITZ |
摘要 |
<p>Cryptographic algorithms based on abnormal binary elliptic curves are public key algorithms having over RSA algorithms the advantage of less time calculation and smaller key size. It has been found that their application in a smart card type environment is vulnerable to DPA (Differential Power Analysis) attacks. The invention consists in the description of countermeasure methods to provide against such DPA attacks. Said countermeasure does not decrease performances and is easily used in a component such as a smart card.</p> |
