Desain S-Box Fleksibel: Regenerasi Konstanta dan Koefisien Fungsi Linier Berbasis CSPRNG Chaos

Abstract: The substitution process in block ciphers usually uses static s-boxes, where the value of each s-box entry is always fixed and the functions are one-to-one. Visually, the dataset pattern in the input is also seen in the output. This will make it easier for cryptanalysts to look at patterns and can predict behavior based on the input. This study designs a flexible s-box where each entry contains a linear function, with constants and coefficients generated by CSPRNG chaos from the key input. The strength of a fl… Show more

“…Research [9] Implements the cubic function f (x) = 3(x 3 − x 2 − x) using xed-point iteration to generate several iterative functions that can be used as random number generators. Research [10] regenerates constants and coe cients of linear functions based on CSPRNG chaos, used as a Flexible S-box Design.…”
