Hash-Chain Fog/Edge: A Mode-Based Hash-Chain for Secured Mutual Authentication Protocol Using Zero-Knowledge Proofs in Fog/Edge [PDF]
Sensors, 2022 Authentication is essential for the prevention of various types of attacks in fog/edge computing. So, a novel mode-based hash chain for secure mutual authentication is necessary to address the Internet of Things (IoT) devices’ vulnerability, as there have been several years of growing concerns regarding their security.

Hey, That's My Model! Introducing Chain & Hash, An LLM Fingerprinting Technique [PDF]
arXivAmid growing concerns over the ease of theft and misuse of Large Language Models (LLMs), the need for fingerprinting models has increased. Fingerprinting, in this context, means that the model owner can link a given model to their original version, thereby identifying if their model is being misused or has been completely stolen.

A Secure Communication Method Based on Message Hash Chain
Applied Sciences, 2022 Traditional network communication methods lack endogenous security mechanisms, which is the root cause of network security problems, e.g., spoofing identity and address forgery. This paper proposes a secure communication method based on the message hash chain, referred to as the chain communication method or MHC method. We use the message hash chain to

Hash-chain-based authentication for IoT
ADCAIJ: Advances in Distributed Computing and Artificial Intelligence Journal, 2016 The number of everyday interconnected devices continues to increase and constitute the Internet of Things (IoT). Things are small computers equipped with sensors and wireless communications capabilities that are driven by energy constraints, since they use batteries and may be required to operate over long periods of time. The majority of these devices

Permutation-Based Hash Chains with Application to Password Hashing [PDF]
IACR Transactions on Symmetric CryptologyHash chain based password systems are a useful way to guarantee authentication with one-time passwords. The core idea dates back to Lamport, and is specified in RFC 1760 as S/Key. At CCS 2017, Kogan et al. introduced T/Key, an improved password system where one-time passwords are only valid for a limited time period.
