Generalized (identity‐based) hash proof system and its applications [PDF]
Security and Communication Networks, 2013 AbstractIn this work, we generalize the paradigm of the hash proof system (HPS) proposed by Cramer and Shoup (EUROCRYPT 2002). In the center of our generalization, we lift a subset membership problem to a distribution‐distinguishing problem. Our generalized HPS clarifies and encompasses all the known public‐key encryption (PKE) schemes that essentially

On Some Approaches to the Solution of the Problem «Useful Proof-of-work for Blockchains»
Моделирование и анализ информационных систем, 2018 The blockchain technology is based on the ”Proof-of-work” principles. The essence of this principle is that some event (for example the bill-to-bill money transaction) becomes significant after the confirmation by a certain computer work.

A branch hash function as a method of message synchronization in anonymous P2P conversations
International Journal of Applied Mathematics and Computer Science, 2016 Currently existing solutions rarely protect message integrity, authenticity and user anonymity without burdening the user with details of key management. To address this problem, we present Aldeon-a protocol for anonymous group conversations in a peer-to-

Miners' Reward Elasticity and Stability of Competing Proof‐of‐Work Cryptocurrencies
International Economic Review, EarlyView.ABSTRACT Proof‐of‐Work cryptocurrencies employ miners to sustain the system through algorithmic reward adjustments. We develop a stochastic model of the multicurrency mining and identify conditions for stable transaction speeds. Bitcoin's algorithm requires hash supply elasticity <$<$1 for stability, while ASERT remains stable for any elasticity and ...

CCA-Secure IB-KEM from Identity-Based Extractable Hash Proof System [PDF]
The Computer Journal, 2013 In this paper, we introduce a general paradigm called identity-based extractable hash proof system (IB-EHPS), which is an extension of extractable hash proof system (EHPS) proposed by Wee (CRYPTO’10).

Removing Erasures with Explainable Hash Proof Systems [PDF]
, 2017 An important problem in secure multi-party computation is the design of protocols that can tolerate adversaries that are capable of corrupting parties dynamically and learning their internal states. In this paper, we make significant progress in this area in the context of password-authenticated key exchange (PAKE) and oblivious transfer (OT) protocols.

Applying FPGA Runtime Reconfiguration to Multi-Hash Proof-of-Work Algorithms
, 2022 In the cryptocurrency mining field, algorithms have been developed to discourage the development of ASICs that greatly out-compete general-purpose hardware in both perfor- mance and power efficiency. A class of algorithms that claims to be ASIC-resistant
