Selective Location Blinding Using Hash Chains [PDF]
, 2011 Location-based applications require a user's movements and positions to provide customized services. However, location is a sensitive piece of information that should not be revealed unless strictly necessary. In this paper we propose a procedure that allows a user to control the precision in which his location information is exposed to a service ...

Hash-chain-based authentication for IoT
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 ...

Digital signatures over hash-entangled chains [PDF]
SN Applied Sciences, 2019 In this work we introduce a new approach for digital signature based on hash chains. The method is supported on the well known security principles of hash functions. Some main advantages of this public key system include security and estimated efficiency through the so called signature chains.

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.

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 ...

Atomic and privacy-preserving cyclic cross-chain protocol based on chameleon hash function
Blockchain: Research and ApplicationsBlockchain-based digital assets have increasingly emerged in recent years, necessitating cross-chain swaps. Hash Time-Lock Contract (HTLC) is a widely used protocol for such swaps; however, simple hash time locks can allow attackers to analyze ...

Fast Counterfeit RFID Tags Detection With Slot Constraints
IEEE 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.

XOR Chain and Perfect Secrecy at the Dawn of the Quantum Era
Cryptography, 2023 In this article, we present a new method that achieves Shannon’s perfect secrecy. To achieve this property, we will introduce the triple XOR cancellation rule. The approach has two execution modes: digital signature and data encryption.
