Carlet and Charpin classi?ed in [5] the set of blockish (n ? 4)- resilient Boolean functions into intravenous feeding di?erent types with respect to the Walsh spectrum and the place of the linear space. base on the classi?cation of RM (3, 6)/RM (1, 6), we completed the classi?cation of the three- markal (n?4)-resilient Boolean function by deriving the corresponding ANF and auto coefficient of correlation spectrum for each of the four types. In the very(prenominal) time, we solved an open chore of [5] by proving that all plateaued boxlike (n ? 4)-resilient Boolean functions have dimension of the linear space match either to n ? 5 or n ? 6. 1 Introduction The properties of quadratic polynomial Boolean functions (i.e, the second order Reed-Muller code RM (2, n)) are comfortably studied, (e.g.

the weight distribution [13], the a?ne equivalence classes [13], the classi?cation of resilient functions [4] and functions compensateing propagation characteristics [16], etc.) However, it is not trivial to extend these results for functions of higher(prenominal) degrees and even for cubic functions. It is important to understan d how the properties behave for the di?erent! degrees of functions. In this paper we focal point on the study of cubic functions which satisfy the highest order of resiliency. resilience is an important property related to (fast) correlation attacks in menstruation ciphers [19, 15], which we de?ne in the next section. In [5], Charpin and Carlet made the ?rst whole step in classifying the set of (n ? 4)-resilient cubic Boolean functions by distinguishing four types of functions with respect...If you want to get a bounteous essay, order it on our website: BestEssayCheap.com
