Highly dispersive substitution box (S‐box) design using chaos
ETRI Journal, 2020 Highly dispersive S‐boxes are desirable in cryptosystems as nonlinear confusion sub‐layers for resisting modern attacks. For a near optimal cryptosystem resistant to modern cryptanalysis, a highly nonlinear and low differential probability (DP) value is ...

Further Results of the Cryptographic Properties on the Butterfly Structures
, 2016 Recently, a new structure called butterfly introduced by Perrin et at. is attractive for that it has very good cryptographic properties: the differential uniformity is at most equal to 4 and algebraic degree is also very high when exponent $e=3$.

Security against differential and linear cryptanalysis for general SPT models
Tongxin xuebao, 2012 To use SP network in stream ciphers safely and efficiently,the ability against differential and linear cryptanalysis of SPT models was studied,where S and T denote different layers for substitution,in which compression could be achieved,and P denotes the

Journal of Mathematics, Volume 2026, Issue 1, 2026.A connection between cryptography and polynomial functions is extremely significant. Mathematical performance of polynomials helps to enhance the cryptographic primitives, which are trustworthy as well as straightforward representation tools, in everyday use. In this research, explicit topological sequences Qf which correspond to degree‐based, distance‐

Generating Graphs Packed with Paths Estimation of Linear Approximations and Differentials
IACR Transactions on Symmetric Cryptology, 2018 When designing a new symmetric-key primitive, the designer must show resistance to known attacks. Perhaps most prominent amongst these are linear and differential cryptanalysis. However, it is notoriously difficult to accurately demonstrate e.g.

A Secure and Robust Blockchain‐Based Medical Image Encryption Approach Using Lorenz Chaotic System
Journal of Sensors, Volume 2026, Issue 1, 2026.Keeping medical images confidential while transmitting is crucial, especially in an open networking environment. One effective approach is blockchain‐based encryption, which provides strong security for sensitive healthcare data. To ensure the greatest levels of medical data integrity and authenticity, our proposed scheme employs a unique Lorenz ...
