Threshold Implementations are known countermeasures defending against side-channel attacks via the use of masking techniques. While sufficient properties are known to defend against first-order side-channel attacks, it is not known how to achieve higher-order security. This work generalizes the Threshold Implementation notion of uniformity and proves it achieves second-order protection. The notion is applied to create a second-order masking of the Present cipher with a low randomness cost.

弹性均匀性:在掩蔽中应用弹性

阈值实现是已知的对策,通过使用掩码技术来防御侧信道攻击。虽然已知足够的特性可以防御一阶边信道攻击,但尚不清楚如何实现更高阶的安全性。这项工作概括了一致性的阈值实现概念,并证明它实现了二阶保护。该概念用于创建具有低随机性成本的当前密码的二阶掩码。
