Project title: Construction and properties of cryptographic Boolean functions
Project description: Optimal Boolean functions are functions with optimal resistance to various cryptographic attacks (such as perfect nonlinear (PN), almost perfect nonlinear (APN), bent, almost bent (AB), crooked functions). In cryptology the security of a cryptosystem is often based on hardness of solving certain mathematical problems. On the other hand, it turns out that to construct optimal Boolean functions for cryptosystems it is often necessary to face mathematical challenges. Indeed, functions with optimal cryptographic properties define optimal objects in algebra, combinatorics, coding theory, finite geometry, sequence design et al. The main aim of this project is to combine computational methods with mathematical methods of the above mentioned theories for construction of optimal Boolean functions.
