This analysis constructs 2-rotation symmetric boolean functions with optimal properties, suggesting enhanced security in cryptographic applications.
2-rotation symmetric Boolean functions have important applications in cryptography. This paper focuses on constructing 2-rotation symmetric Boolean functions having nice cryptographic properties. Firstly, we present some new constructions of 2-rotation symmetric bent functions with optimal algebraic degree. Secondly, we propose a class of 2-rotation symmetric resilient functions having high nonlinearity and optimal algebraic degree.
