7. Strict avalanche and propagation criteria🔗

Carlet's Chapter 8 develops propagation criteria through derivative balancedness, Walsh-square identities, nonlinearity bounds, constructions, coordinate restrictions, and criteria of order. Throughout, V_n=\mathbb F_2^n and W_f denotes the unnormalized Walsh transform.
