Symmetric Encryption Scheme Based on Quasigroup Using Chained Mode of Operation

S Kumar, H Singh, I Gupta, AJ Gupta - arxiv preprint arxiv:2408.04490, 2024 - arxiv.org
In this paper, we propose a novel construction for a symmetric encryption scheme, referred
as SEBQ which is based on the structure of quasigroup. We utilize concepts of chaining like …

Quantum secure digital signature scheme based on multivariate quadratic quasigroups (MQQ)
