A Provably Secure Authentication Protocol Based on PUF and ECC for IoT Cloud‐Edge Environments

IET Information Security, Volume 2025, Issue 1, 2025.
The Internet of Things (IoT) cloud model provides an efficient scheme for rapid collection, storage, processing, and analysis of massive node data, and its application has gradually expanded to key areas such as healthcare and transportation. However, the security issues of open channel transmission in IoT still persist. Researchers have proposed a lot

ToFA: Towards Fault Analysis of GIFT and GIFT-like Ciphers Leveraging Truncated Impossible Differentials

Transactions on Cryptographic Hardware and Embedded Systems
In this work, we introduce ToFA, the first fault attack (FA) strategy that attempts to leverage the classically well-known idea of impossible differential cryptanalysis to mount practically verifiable attacks on bit-oriented ciphers like GIFT and ...

NoLIEM: A Novel Lightweight Image Encryption Method for Resource‐Constrained IoT Devices

IET Information Security, Volume 2025, Issue 1, 2025.
The expanded use of Internet of Things (IoT) devices in smart homes, industrial automation, healthcare, and smart cities has increased the risk of unauthorized access, data breaches, and man‐in‐the‐middle attacks. Traditional encryption methods like AES and RSA are too energy‐ and processing‐intensive for IoT devices.

Revisiting the shuffle of generalized Feistel structure

Cybersecurity
The Generalized Feistel Structure ( $$\texttt{GFS}$$ GFS ) is one of the most widely used frameworks in symmetric cipher design. In FES 2010, Suzaki and Minematsu strengthened the cryptanalysis security of $$\texttt{GFS}$$ GFS by searching for shuffles ...

A Novel Method of Data Protection Through DNA Chromosome Databases

Applied Computational Intelligence and Soft Computing, Volume 2025, Issue 1, 2025.
With the advancement of the digital age, data have become insecure, which requires techniques to secure data. Deoxyribonucleic acid (DNA) has become an increasingly secure technology for storing next‐generation digital data. DNA provides superior capabilities due to its high and efficient storage capacity and long lifespan.

Cryptanalysis: Theory Versus Practice

IACR Transactions on Symmetric Cryptology
Most modern cryptanalysis results are obtained through theoretical analysis, often relying on simplifications and idealized assumptions. In this work, we use the parallel computational power of GPUs to experimentally verify a small portion of the ...

A Secure Way of Communication for Smart Grid Networks

International Journal of Distributed Sensor Networks, Volume 2025, Issue 1, 2025.
In 2021, Khan et al. suggested a scheme based on smart grid networks. They deployed the random oracle model to justify the security of their scheme formally. They also verified the security of the scheme using the AVISPA software tool. We studied this scheme and found some security issues. The scheme suffers from a confidentiality breach attack.

Differential-linear and Impossible Differential Cryptanalysis of Round-reduced Scream

Proceedings of the 14th International Joint Conference on e-Business and Telecommunications, 2017
In this work we focus on the tweakable block cipher Scream, We have analysed Scream with the techniques, which previously have not been applied to this algorithm, that is differential-linear and impossible differential cryptanalysis. This is work in progress towards a comprehensive evaluation of Scream.
