DOUBLE-A – A NEW CRYPTOGRAPHIC HASH FUNCTION (ITS DESIGN)

Abstract

This paper examines the outline decisions of the sponge constructed cryptographic hash function Double-A. Firstly, the relative favorable circumstances of why a stream mode cipher is utilized instead of a block mode are given. Furthermore, a portrayal of what a sponge function is, the way it is designed and what are its fundamental components. At long last, after a brief review of the Salsa20 stream cipher and its structure, the decisions of the states width, rounds and operations in the pseudorandom function f are talked about in subtle element to show how and why they are utilized as a part of the stage of Double-A.
