Construction of Resilient Functions with Multiple Cryptographic Criteria
In this paper, we describe a method to construct (n, m, t) resilient functions which satisfy multiple cryptographic criteria including high nonlinearity, good resiliency, high algebraic degree, and nonexistence of nonzero linear structure. Given a [u, m, t+1] linear code, we show that it is possible to construct (n, m, t) resilient functions with multiple good cryptographic criteria, where 2m<u<n.
Enumeration of Balanced Symmetric Functions over GF(p)
It is proved that the construction and enumeration of the number of balanced symmetric functions over GF(p) are equivalent to solving an equation system and enumerating the solutions. Furthermore, we give an lower bound on number of balanced symmetric functions over GF(p), and the lower bound provides best known results.
