It is well known that, the block algorithms supply security through its components (S-boxes, boolean functions, polynomials). Depending on the characteristics and properties of their components, the block algorithms provide a certain level of security. If the algorithm components are weak, then the algorithm may be weak. This paper intends to approach a part of this issue by analyzing the way in which the S-boxes' properties influence the strength of the algorithms.
