Malicious KGC attacks in certificateless cryptography

, 2007
Identity-based cryptosystems have an inherent key escrow issue, that is, the Key Generation Center (KGC) always knows user secret key. If the KGC is malicious, it can always impersonate the user.

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.
