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 ...

A Secure Communication Method Based on Message Hash Chain [PDF]
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.

Individual displacements in hashing with coalesced chains [PDF]
Combinatorics, Probability and Computing, 2005 We study the asymptotic distribution of the displacements in hashing with coalesced chains, for both late-insertion and early-insertion. Asymptotic formulas for means and variances follow. The method uses Poissonization and some stochastic calculus.

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.

Reversible and Plausibly Deniable Covert Channels in One-Time Passwords Based on Hash Chains [PDF]
Applied Sciences, 2021 Covert channels enable stealthy communications over innocent appearing carriers. They are increasingly applied in the network context. However, little work is available that exploits cryptographic primitives in the networking context to establish such ...

The application of hash chains and hash structures to cryptography
, 2009 In this thesis we study how hash chains and other hash structures can be used in various cryptographic applications. In particular we focus on the applications of entity authentication, signatures and key establishment. We study recursive application of hash functions to create hash chains, hash trees and other hash structures. We collate all these to

Efficient Constructions for One-Way Hash Chains [PDF]
, 2005 Abstract: "One-way chains are an important cryptographic primitive in many security applications. Lamport first proposed to use one-way chains for one-time password authentication [19]. Subsequently, researchers proposed one-way chains as a basic building block for digital cash, for extending the lifetime of digital certificates, for constructing one ...
