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.
