The security of resource-constrained devices is critical in the IoT field, given that everything
is interconnected. Therefore, the National Institute of Standards and Technology (NIST) …

Abstract The National Institute of Standards and Technology (NIST) initiated a public
standardization process to select one or more schemes that provide Authenticated …

An authentication protocol is one of the fundamental security mechanisms in distributed
systems to ensure the integrity and trust level of the nodes during communication. Since …

Electronic devices are connected now more than ever with the prevalence of the Internet of
Things. The ever-increasing communication between these lightweight devices presses for …

We study the provable security claims of two NIST Lightweight Cryptography (LwC) finalists,
GIFT-COFB and Photon-Beetle, and present several attacks whose complexities contradict …

GIFT-COFB is a finalist of NIST Lightweight cryptography project that aims at standardizing
authenticated encryption schemes for constrained devices. It is a block cipher-based …

The size of the authentication tag represents a significant overhead for applications that are
limited by bandwidth or memory. Hence, some authenticated encryption designs have a …

This study focuses on the implementation of the GIFT-COFB lightweight cryptography
algorithm to enhance the security of kart telemetry, specifically for the steering angle and …
