In this work, work has been carried out to systematize and analyze the main criteria that S-boxes must satisfy in order to ensure a high level of cryptographic strength of symmetric cryptographic algorithms. The set of all possible criteria for their assessment can be divided into unconditional and conditional. The unconditional criteria are those that must be met by S-boxes in order to ensure their resistance to major cryptanalytic attacks. Conditional refers to additional criteria that S-boxes must meet in order to compare S-boxes that meet the unconditional criteria. The paper presents a reasonable choice of a set of unconditional criteria that determine the optimality of S-boxes.
