PRINCE密码算法是于ASIA CRYPT 2012提出的轻量级的加密算法,用于在物联网环境下保护RFID标签以及智能卡等设备的通信安全。提出并讨论了一种针对PRINCE算法的差分故障分析方法。该方法采用半字节故障模型,对PRINCEcore最后一轮进行了差分故障分析。实验结果表明,在PRINCEcore最后一轮导入半字节随机故障,4次故障注入可实现对PRINCE算法PRINCEcore部分的64位轮密钥的恢复。因此,未加防护措施的PRINCE加密系统将难以抵御差分故障分析手段。

PRINCE is a lightweight cryptographic algorithm proposed in CRYPT ASIA 2012,for the protection of RFID tags and the communication security of the devices such as smart cards in the Internet of things,as smart cards.A differential fault analysis method was proposed and discussed in this paper.The method is based on the PRINCE algorithm.In this method,a semi-byte fault model is adopted,and the differential fault analysis is carried out on the last PRtNCEcore.Experimental results show that the semi-byte random fault is injected into the last round of the PRINCEcore,the key(k1) can be cracked by 4...
