Low-latency has been an important criterion in the design of block ciphers, especially in lightweight cryptography for IoT (Internet of Things) constrained devices to ensure secure real-time data transmission with limited resources. However, the design of most low-latency block ciphers today employ the so-called SPN (Substitution Permutation Network) structure with a few exceptions such as the SCARF cipher. In this article, by adopting the ideas of parallel execution for bridging the gap in latency between the standard Feistel and SPN structures, we propose a new low-latency cipher that uses t...
