Two basic requirements must be met to encrypt data. These requirements are confusion and diffusion properties. In particular, block cipher algorithms are based on a cryptographic component known as substitution-box to provide the need for confusion. Therefore, attack scenarios generally focus on this cryptographic component. There are alternative design approaches for substitution-box design. It is known that each design approach has several advantages and disadvantages. In this study, an alternative method is proposed to address the problems of the substitution-box design approach based on random selection. The success of the proposed method has been tested in three different scenarios. Analysis results for these three scenarios showed that generated substitution-box provides performance increase for nonlinearity criterion from s-box design criteria. Successful results achieved; It points out that improvement cryptographic components can be used in a variety of practical applications such as block ciphers, masks to prevent side-channel attacks, random number generators, and image encryption algorithms.

加密数据必须满足两个基本要求。这些要求是混淆和扩散特性。特别是，分组密码算法基于称为替换盒的加密组件，以提供混淆的需要。因此，攻击场景通常集中在这个加密组件上。替代盒设计有多种替代设计方法。众所周知，每种设计方法都有几个优点和缺点。在这项研究中，提出了一种替代方法来解决基于随机选择的替代盒设计方法的问题。所提出的方法的成功已经在三个不同的场景中进行了测试。这三种情况的分析结果表明，生成的替换框为 s-box 设计标准的非线性标准提供了性能提升。取得成功的成果；它指出改进的密码组件可用于各种实际应用，例如分组密码、防止侧信道攻击的掩码、随机数生成器和图像加密算法。
