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…

Primitive transformation shift registers over finite fields
Ambrish Awasthi, Rajendra K Sharma
We consider the problem of existence and enumeration of primitive TSRs of order n over any finite field. Here we prove the existence of primitive TSRs of order two over finite fiel…

Primitive transformation shift registers of order two over fields of characteristic two
Ambrish Awasthi, Rajendra K. Sharma
We consider the problem of enumeration of primitive TSRs of order n over any finite field. Here we prove the existence of primitive TSRs of order two over binary field extensions.…
