Paper 2023/1632 , University of Bergen , University of Bergen , University of Bergen , Naval Postgraduate School , KU Leuven, University of Bergen The algebraic degree of a vectorial Boolean function is one of the main parameters driving the cost of its hardware implementation. Thus, finding decompositions of functions into sequences of functions of lower algebraic degrees has been explored to reduce the cost of implementations.

Paper 2023/1081 ARITHMETIZATION-ORIENTED APN FUNCTIONS , University of Bergen , University of Bergen Abstract Recently, many cryptographic primitives such as homomorphic encryption (HE), multi-party computation (MPC) and zero-knowledge (ZK) protocols have been proposed in the literature which operate on prime field $\mathbb{F}_p$ for some large prime $p$. Primitives that are designed using such operations are called arithmetization-oriented primitives.
