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

Multiple Impossible Differentials Attack on AES-192

IEEE Access, 2019
The security of AES-192 against multiple impossible differentials attack is studied in this paper. Based on two types of impossible differentials for 4-round AES, two 7-round attack trails of AES-192 with the same plaintext and ciphertext difference ...

Extended Generalized Feistel Networks using Matrix Representation [PDF]

, 2013
International audienceWhile Generalized Feistel Networks have been widely studied in the literature as a building block of a block cipher, we propose in this paper a unified vision to easily represent them through a matrix representation. We then propose

On the Security of the Yi-Tan-Siew Chaos-Based Cipher [PDF]

, 2004
This paper presents a comprehensive analysis on the security of the Yi-Tan-Siew chaotic cipher proposed in [IEEE TCAS-I 49(12):1826-1829 (2002)]. A differential chosen-plaintext attack and a differential chosen-ciphertext attack are suggested to break ...

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.

Security Analysis of SKINNY under Related-Tweakey Settings

IACR Transactions on Symmetric Cryptology, 2017
In CRYPTO’16, a new family of tweakable lightweight block ciphers - SKINNY was introduced. Denoting the variants of SKINNY as SKINNY-n-t, where n represents the block size and t represents the tweakey length, the design specifies t ∈ {n, 2n, 3n}. In this

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.

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.
