A substitution box (s-box) is a nonlinear component function used in most block ciphers. It must fulfill several cryptographic properties such as high nonlinearity, low differential uniformity and complex algebraic expression to resist against linear, differential and interpolation attacks. In this paper, we extend and improve the s-box construction method(More)
In this paper, we explore a heuristic method called the bee waggle dance to construct cryptographically strong S-boxes. The S-boxes exhibit good cryptographic properties such as high nonlinearity, low differential uniformity and high algebraic degree. The method involves the use of a trinomial power function as the initial S-box. The elements in the S-box(More)
Cryptographic hash function is a combination of several components including a compression function which is made up of a few underlying elements such as Boolean functions and permutation. Some properties of Boolean functions are very helpful for determining sufficient conditions used in modern attack for hash functions. We study these underlying elements(More)
