Abstract:We investigate the concept of S0 equivalent class, n-variable Boolean functions up to the addition of a symmetric function null in 0n and 1n, as a tool to study weightwise perfectly balanced functions. On the one hand we show that weightwise properties, such as being weightwise perfectly balanced, the weightwise nonlinearity and weightwise algebraic immunity, are invariant of these classes. On the other hand, we analyse the variation of global parameters inside the same class, showing for example that there is… Show more
