The expansion of worldwide networking has created new possibilities for management,
development, and presentation in the form of digital data. The uncomplicated accessibility to …

In recent years, a large number of S-Box design schemes have been proposed. However,
after detection we found that most of them contain fixed point or reverse fixed point, which …

A symmetric block cipher employing a substitution–permutation duo is an effective technique
for the provision of information security. For substitution, modern block ciphers use one or …

In this paper, we propose to present a novel technique for designing cryptographically
strong substitution-boxes using cubic polynomial mapping. The proposed cubic polynomial …

The influential application of substitution boxes in secure communication and multimedia
security attracted researchers to construct more robust substitution boxes. The advantage of …

This work reports a novel chaos-based affine transformation generation method, which is
based on rotational matrices to design strong key-based S-boxes. Chaotic logistic map's …

Abstract Information security algorithms provide praxis for security to the different forms of
data. Data are transmitted in different forms like ASCII text, UNICODE text, audio, video …

In this paper, a method to enhance the dynamic characteristics of one-dimension (1D)
chaotic maps is first presented. Linear combinations and nonlinear transform based on …

This paper proposes to present a novel group theoretic approach of improvising the
cryptographic features of substitution-boxes. The approach employs a proposed finite …

Data encryption with substitution-box (S-box) is now widely regarded as the most secure
method of communicating in order to prevent unauthorized access to sensitive and …
