Towards quantum‐safe blockchain: Exploration of PQC and public‐key recovery on embedded systems
IET Blockchain, Volume 5, Issue 1, January/December 2025.This paper addresses the need for quantum‐safe blockchain solutions specifically for embedded systems by integrating Post‐Quantum Cryptography (PQC) into blockchain frameworks. We propose a quantum‐secure blockchain architecture using NIST‐standardized PQC algorithms, finding Falcon‐512 to be optimal for embedded environments due to its security and ...

A New Trick for Polynomial Multiplication
Transactions on Cryptographic Hardware and Embedded SystemsIn this paper we present a novel transformation strategy for polynomial multiplications and apply it to NTRU Prime, specifically the parameter sets sntrup761 and ntrulpr761 working in the ring Z4591[x]/⟨x761−x−1⟩.

Design of Linkable Ring Signature Scheme Based on the MP‐LWE Problem and Its Application in IoV
IET Information Security, Volume 2025, Issue 1, 2025.Ensuring the information security and privacy of users in the Internet of Vehicles (IoV) is crucial for gaining user trust and promoting the application of vehicular networks. This article designs an efficient linkable ring signature (LRS) scheme on the basis of the middle‐product learning with errors (MP‐LWE) problem and applies it to vehicular ...

Revisiting LWR: A Novel Reduction Through Quantum Approximations
IET Information Security, Volume 2025, Issue 1, 2025.Pseudorandom functions (PRFs) are a very important tool in cryptography, and the learning with rounding (LWR) problem is one of the main issues in their construction. LWR problem, is to find s∈Zqn from ⌊As⌋p, where A∈Zqm×n and ⋅p:Zq→Zp is the rounding function.

Improved FHE Bootstrapping and Its Applications in Discretized Neural Networks
IET Information Security, Volume 2025, Issue 1, 2025.The inefficiency of bootstrapping is the primary bottleneck preventing fully homomorphic encryption (FHE) from practical applications. One of the main obstacles to improving the bootstrapping performance using hardware acceleration is the large storage overhead of the bootstrapping keys.

IET Information Security, Volume 2025, Issue 1, 2025.The current multikey fully homomorphic encryption (MKFHE) needs to add exponential noise in the distributed decryption phase to ensure the simulatability of partial decryption. Such a large noise causes the ciphertext modulus of the scheme to increase exponentially compared to the single‐key fully homomorphic encryption (FHE), further reducing the ...
