Cryptographic hash functions based on Artificial Life

چکیده

There is a long history of cryptographic hash functions, i.e. functions mapping variable-length strings to fixed-length strings, with such functions also expected to enjoy certain security properties. Hash functions can be effected via modular arithmetic, recursive permutation-based schemes, chaotic mixing, and so on. Herein we introduce the notion of an Artificial Life (or ALife) hash function (ALHF), whereby the requisite mixing action of a good hash function is accomplished via typical ALife rules that give rise to complex system evolution. Various security tests have been run, and the results reported herein, for exemplary ALHFs.

Compressed Image Hashing using Minimum Magnitude CSLBP

Image hashing allows compression, enhancement or other signal processing operations on digital images which are usually acceptable manipulations. Whereas, cryptographic hash functions are very sensitive to even single bit changes in image. Image hashing is a sum of important quality features in quantized form. In this paper, we proposed a novel image hashing algorithm for authentication which i...

Lightweight 4x4 MDS Matrices for Hardware-Oriented Cryptographic Primitives

Linear diffusion layer is an important part of lightweight block ciphers and hash functions. This paper presents an efficient class of lightweight 4x4 MDS matrices such that the implementation cost of them and their corresponding inverses are equal. The main target of the paper is hardware oriented cryptographic primitives and the implementation cost is measured in terms of the required number ...

On High-Rate Cryptographic Compression Functions

The security of iterated hash functions relies on the properties of underlying compression functions. We study highly efficient compression functions based on block ciphers. We propose a model for highrate compression functions, and give an upper bound for the rate of any collision resistant compression function in our model. In addition, we show that natural generalizations of constructions by...
