A Secure Cryptocurrency Scheme Based on Post-Quantum Blockchain

open access: yesIEEE Access, 2018
Nowadays, blockchain has become one of the most cutting-edge technologies, which has been widely concerned and researched. However, the quantum computing attack seriously threatens the security of blockchain, and related research is still less. Targeting

Review of Chosen Isogeny-Based Cryptographic Schemes

open access: yesCryptography, 2022
Public-key cryptography provides security for digital systems and communication. Traditional cryptographic solutions are constantly improved, e.g., to suppress brute-force attacks.

Haraka v2 – Efficient Short-Input Hashing for Post-Quantum Applications

open access: yesIACR Transactions on Symmetric Cryptology, 2017
Recently, many efficient cryptographic hash function design strategies have been explored, not least because of the SHA-3 competition. These designs are, almost exclusively, geared towards high performance on long inputs.

PUF-Based Post-Quantum CAN-FD Framework for Vehicular Security

open access: yesInformation, 2022
The Controller Area Network (CAN) is a bus protocol widely used in Electronic control Units (ECUs) to communicate between various subsystems in vehicles. Insecure CAN networks can allow attackers to control information between vital vehicular subsystems.

On the Security of the Dandelion Protocol

open access: yesMathematics, 2022
In this paper, we review the peer-to-peer blockchain transaction protocol, Dandelion, and develop an oracle-based model for its network and security. We formalize a series of security and functional criteria, such as unforgeability, non-repudiation, and ...

Post-quantum security of the sponge construction.. Post-Quantum Cryptography. [PDF]

open access: yesPQCrypto 2018, 2018
We investigate the post-quantum security of hash functions based on the sponge construction. A crucial property for hash functions in the post-quantum setting is the collapsing property (a strengthening of collision-resistance). We show that the sponge construction is collapsing (and in consequence quantum collision-resistant) under suitable ...

A New Identification Scheme based on Syndrome Decoding Problem with Provable Security against Quantum Adversaries [PDF]

open access: yesJournal of Universal Computer Science, 2019
Recently, in order to guarantee security against quantum adversaries, several identification (ID) schemes based on computational problems which are supposed to be hard even for quantum computers have been proposed. However, their security are only proven

Post-Quantum Signature Scheme Based on the Root Extraction Problem over Mihailova Subgroups of Braid Groups

open access: yesMathematics, 2023
In this paper, by introducing an isomorphism from the Mihailova subgroup of F2×F2 to the Mihailova subgroups of a braid group, we give an explicit presentation of Mihailova subgroups of a braid group.

Evaluation of Post-Quantum Distributed Ledger Cryptography

open access: yesThe Journal of The British Blockchain Association, 2019
This paper evaluates the current cybersecurity vulnerability of the prolific use of Elliptical Curve Digital Signature Algorithm (ECDSA) cryptography in use by the Bitcoin Core, Ethereum, Bitcoin Cash, and enterprise blockchains such as ...

SPEEDY Quantum Circuit for Grover’s Algorithm

open access: yesApplied Sciences, 2022
In this paper, we propose a quantum circuit for the SPEEDY block cipher for the first time and estimate its security strength based on the post-quantum security strength presented by NIST.
