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 ...

Cryptanalysis of Keyword Confidentiality in a Searchable Public‐Key Encryption Scheme Against Malicious Server

IET Information Security, Volume 2025, Issue 1, 2025.
Public‐key authenticated encryption with keyword search (PAEKS) is a novel cryptographic primitive to resist against keyword‐guessing attacks (KGAs) and preserve the privacy of keywords in both ciphertexts and trapdoors. Recently, a designated‐server PAEKS (dPAEKS) scheme was proposed to withstand KGAs.
