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

Sensors (Basel), 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 ...

A Secure Communication Method Based on Message Hash Chain

Applied Sciences (Switzerland), 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.

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

IACR 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

IEICE 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

IEICE 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.
