要約(英語): In devices that are used for RFID tags and sensor networks, the number of available hardware resources is extremely small. Since there is a risk of information leakage from these devices, the data they handle must be enciphered. A lightweight block cipher must be used in these devices, due to their resource constraints. Although the encryption algorithms are theoretically safe, it has been recently reported that confidential information could be illegally revealed when the encryption algorithms are used in electronic circuits. In particular, fault analysis attacks have become extremely serious problems. Fault analysis attacks intentionally generate operation errors during the encryption processing and illegally obtain confidential information by pairing an incorrect cipher text and a correct cipher text. To secure the safety of lightweight block ciphers in the future, the tamper resistance against fault analysis attacks must be verified. The present study proposes a new fault analysis method for PRINCE. The proposed method introduces hierarchical attack model using statistical processing to reveal secret keys. Simulation results prove the validity of the proposed method.
