Abstract(in English) | There is a potential that the secret information on an encryption LSI is leaked from a scan chain. There are many countermeasures against scan based attack. When we design a circuit, we need to evaluate a security of the circuit applied these countermeasures quantitatively and choose the best one. However, it is not discussed a quantitative security evaluation against scan based attack so much. In this paper, we propose a quantitative security evaluation method. In this method, we evaluate security using a mutual information between the obtained information which an attacker can obtain and the secret information which an attacker wants to get as an evaluation index. We evaluate securities of DES circuits with different configurations using the proposed method and show quantitatively that the security of a circuit depends on its configuration. |
