A NEW HASH ALGORITHM$:$ Khichidi$-$1

Natarajan Vijayarangan

Abstract: This is a technical report describing a new hash algorithm called Khichidi-1 and has been written in response to a Hash competition (SHA-3) called by National Institute of Standards and Technology (NIST), USA. This algorithm generates a condensed representation of a message called a Message Digest.

A group of functions used in the development of Khichidi-1 is described, followed by a detailed explanation of preprocessing approach. Differences between Khichidi-1 and NIST SHA-2, the algorithm that is in use widely, have also been highlighted. Analytical proofs, implementations with examples, various attack scenarios, entropy tests, security strength and computational complexity of the algorithm are described as separate sections in this document.
