Practical Preimage Attack on 5-Round Keccak[r=640, c=160]

IACR Transactions on Symmetric Cryptology
Internal differential cryptanalysis has recently yielded a series of new results in the preimage cryptanalysis of round-reduced Keccak. While these existing attacks share a similar high-level framework, they differ in their technical details. This paper

A Fast Search Method for 3‐Share Second‐Order Masking Schemes for Lightweight S‐Boxes

IET Information Security, Volume 2025, Issue 1, 2025.
Masking schemes are widely adopted strategies for countering side‐channel analysis (SCA) attacks. The initial hardware masking strategy, threshold implementation (TI), provides robust security against glitches in hardware platforms. The minimum number of shares required for a TI scheme depends not only on the desired security order but also on the ...

Enhancing Medical Images Security and Efficiency With Adaptive Compressed Sensing and SHA‐3 in Telemedicine

International Journal of Biomedical Imaging, Volume 2025, Issue 1, 2025.
Security issues of telemedicine‐based secure transmission of medical images find a very thin line drawn between diagnostic acceptability and cybersecurity. Partial but imperfect solutions emerge. JPEG2000 and HEVC concentrate only on compression, failing to provide any security consideration.

Optimized Design and Implementation of CRYSTALS‐KYBER Based on MLWE

Security and Communication Networks, Volume 2025, Issue 1, 2025.
CRYSTALS‐KYBER is a postquantum key exchange mechanism based on the MLWE problem. At present, it is a major challenge to realize CRYSTALS‐KYBER with high‐performance and low‐resource consumption on the FPGA platform. The design proposed in this paper aims at the high efficiency implementation of CRYSTALS‐KYBER based on the MLWE scheme.
