Hash-Chain Fog/Edge: A Mode-Based Hash-Chain for Secured Mutual Authentication Protocol Using Zero-Knowledge Proofs in Fog/Edge [PDF]

open access: yesSensors, 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 ...

Fast Verification of Hash Chains [PDF]

open access: yesLecture Notes in Computer Science, 2004
A hash chain is a sequence of hash values x i = hash(x i − 1) for some initial secret value x 0. It allows to reveal the final value x n and to gradually disclose the pre-images x n − 1, x n − 2, ... whenever necessary. The correctness of a given value x i can then be verified by re-computing the chain and comparing the result to x n .

A Secure Communication Method Based on Message Hash Chain

open access: yesApplied 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.

On Fast Verification of Hash Chains

open access: yesLecture Notes in Computer Science, 2010
A hash chain H for a hash function hash(·) is a sequence of hash values 〈xn, xn−1,..., x0 〉, where x0 is a secret value, xi is generated by xi=hash(xi−1) for 1≤i≤n, and xn is a public value. Hash values of H are disclosed gradually from xn−1 to x0. The correctness of a disclosed hash value xi can be verified by checking the equation $x_n \stackrel{?}{=}

Permutation-Based Hash Chains with Application to Password Hashing [PDF]

open access: yesIACR Transactions on Symmetric Cryptology
Hash 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.

Energy-Efficient Hash Chain Traversal

open access: yesIEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2011
A hash chain H for a one-way hash function h(·) is a sequence of hash values , where vn is a secret value, vi is generated by vi=h(vi+1) for i=n-1,n-2,...,0 an0d v0 is a public value. A hash chain traversal algorithm T computes and outputs the hash chain H, returning vi in time period (called round) i for 1≤i≤n.

Generalized Hash Chain Traversal with Selective Output

open access: yesIEICE Transactions on Information and Systems, 2010
A hash chain H for a one-way hash function h(·) is a sequence of hash values , where v0 is a public value, vn a secret value, and vi =h(vi+1). A hash chain traversal algorithm T computes and outputs the hash chain H, returning vi in time period (called round) i for 1 ≤ i ≤ n.

Fast Counterfeit RFID Tags Detection With Slot Constraints

open access: yesIEEE Access, 2023
RFID tags are prone to counterfeit attacks in supply chain scenarios. The attacker often uses counterfeit tags to replace stolen tags to avoid being detected by the inventory process.
