Lightweight Key-Dependent Dynamic S-Boxes based on Hyperelliptic Curve for IoT Devices
摘要：
安全性是物联网（IoT）的主要问题之一。加密在使这些系统安全方面起着限制作用。替换盒（S-Box）在分组加密方法中有着重要的作用。由于物联网节点的资源容量有限，提供轻量级的S-Box是一个具有挑战性的问题。提出了一种基于超椭圆曲线的密钥相关S盒。建议的S盒分析评估使用性能标准，包括双射，非线性，严格的雪崩效应，和代数度。评价结果表明，所提出的S盒生成算法是生成密码学强S盒的有效方法。
英文摘要：
Security is one of the main issues in Internet of Things (IoT). Encryption plays a curtail role in making these systems secure. Substitution Box (S-Box) has an effective impact in block encryption methods. Due to the restricted resource capacities of IoT nodes, providing a lightweight S-Box is a challenging problem. This paper presents a key-dependent S-Box using Hyperelliptic curve. The proposed S-Box is analytically evaluated using performance criteria including bijection, nonlinearity, strict avalanche effect, and algebraic degree. The evaluation results endorse that the offered S-Box production algorithm is considerably an effective way to generate cryptographic strong S-Box.
