An Improved 3-Quasigroup based Encryption Scheme
The Crypto-community is always in search of new strong crypto-primitives to handle the present security threats and for providing efficient secure digital communication. One of the main goals of the cryptographer is to make an encryption scheme computationally fast with optimized use of memory and high cryptographic complexity. In this direction n-quasigroups (n = 2, 3) are considered as a clas...
متن کاملEvolving Quasigroups by Genetic Algorithms
Quasigroups are a well-known combinatorial design equivalent to more familiar Latin squares. Because all possible elements of a quasigroup occur with equal probability, it makes it an interesting tool for the application in computer security and for production of pseudorandom sequences. Most implementations of quasigroups are based on look-up table of the quasigroup, on system of distinct repre...

متن کاملTesting Quasigroup Identities using Product of Sequence
Non-associative quasigroups are well known combinatorial designs with many different applications. Many cryptographic algorithms based on quasigroups primitives have been published. There are several classifications of quasigroups based on their algebraic properties. In this paper we propose a new classification of quasigroups based upon strings (product elements) obtained by a product of a seq...
متن کاملA Novel Quasigroup Substitution Scheme for Chaos Based Image Encryption
A During last two decades, there has been a prolific growth in the chaos based image encryption algorithms. Up to an extent these algorithms have been able to provide an alternative to exchange large media files (images and videos) over the networks in a secure way. However, there have been some issues with the implementation of chaos based image ciphers in practice. One of them is reduced/smal...
