Abstract(in English) | When a cryptographic circuit is used, it is extremely important to verify its tamper resistance against side-channel attacks. Side-channel attacks illegally obtain confidential information using physical information, such as power consumption and electromagnetic waves generated during the encryption processing. In particular, power analysis attacks using power consumption can easily analyze confidential information. The masking is a typical measure against power analysis attacks. In this method, the correlation between power consumption and confidential information is masked by adding random numbers to intermediate data of encryption. However, there are no reports on relationship between the period and accuracy of the random number and the tamper resistance in the masking. This study verifies the tamper resistance of the masking using several random number generators. |
