INRU: A Quasigroup Based Lightweight Block Cipher
Sharwan K. Tiwari, Ambrish Awasthi, Sucheta Chkrabarti +1
In this paper, we propose a quasigroup based block cipher design. The round functions of the encryption and decryption algorithms use quasigroup based string transformations. We sh…

Algebraic Properties of Subquasigroups and Construction of Cryptographically Suitable Finite Quasigroups
V. A. Artamonov, Sucheta Chakrabarti, Sharwan K. Tiwari +1
In this paper, we identify many important properties and develop criteria for the existence of subquasigroups in finite quasigroups. Based on these results, we propose an effective…
