An efficient construction of key-dependent substitution box based on chaotic sine map
International Journal of Distributed Sensor Networks, 2019 A substitution box is a core component of the popular symmetric-key algorithms. However, the major problem of the conventional substitution boxes is the statistic behavior, which is employed as a fixed-size lookup table.

Distribusi Difference dari S-Box Berbasis Fungsi Balikan Pada GF(28)
Jurnal Matematika, 2016 Substitution-box (s-box) is a basic component of block cipher which performs a substitution. Two powerful cryptanalysis techniques applied to block ciphers are linear cryptanalysis and differential cryptanalysis.

Understanding the Technological Substitution by Hybrid Modelling Practice: a Methodological Approach
Chemical Engineering Transactions, 2015 Various novel climate technologies and eco-innovations have already reached a mature state, but they diffuse slowly into the market. Due to this slow process the mitigation of climate change does not take the most effective path.
