Impossible Differential Cryptanalysis of Surge

IOP Conference Series: Earth and Environmental Science, 2020
Abstract In 2018, Li Lang et al. proposed a new lightweight block cipher which is called Surge. Its block size is 64-bit, and the length of key size is 64/80/128-bit, respectively. They also proved that the cipher has good performance on security and effectively resists on differential attack, linear attack and algebraic attack.

Subspace Trail Cryptanalysis and its Applications to AES

IACR Transactions on Symmetric Cryptology, 2017
We introduce subspace trail cryptanalysis, a generalization of invariant subspace cryptanalysis. With this more generic treatment of subspaces we do no longer rely on specific choices of round constants or subkeys, and the resulting method is as such a ...

Improved Security Evaluation of SPN Block Ciphers and its Applications in the Single-key Attack on SKINNY

IACR Transactions on Symmetric Cryptology, 2020
In this paper, a new method for evaluating the integral property, truncated and impossible differentials for substitution-permutation network (SPN) block ciphers is proposed. The main assumption is an explicit description/expression of the internal state

Cryptanalysis of Reduced round SKINNY Block Cipher

IACR Transactions on Symmetric Cryptology, 2018
SKINNY is a family of lightweight tweakable block ciphers designed to have the smallest hardware footprint. In this paper, we present zero-correlation linear approximations and the related-tweakey impossible differential characteristics for different ...

The differential fault analysis on block cipher FeW

Cybersecurity, 2022
Feather weight (FeW) cipher is a lightweight block cipher proposed by Kumar et al. in 2019, which takes 64 bits plaintext as input and produces 64 bits ciphertext. As Kumar et al.

SKE2SG: A Secure Key Establishment Scheme for Smart Grid Cyber‐Physical Systems Based on Elliptic Curve Cryptography

IET Cyber-Physical Systems: Theory &Applications, Volume 11, Issue 1, January/December 2026.
Recent proposals by Mahmood et al., Braeken et al., and Chaudhry et al. aimed at establishing secure communication in AMI, asserting their methods fulfil the requisite security criteria. This paper, however, reveals that each of these proposals exhibits security vulnerabilities and lacks sufficient features for deployment.

Enhancing E‐Commerce Security Based on Involution Function Using Twin Key AES Cipher

IET Information Security, Volume 2026, Issue 1, 2026.
In the realm of surging e‐commerce data and increasing digital transactions, ensuring end‐to‐end security is paramount to protect sensitive information and maintain user trust. The Advanced Encryption Standard (AES), a cornerstone of network security, relies on symmetric key encryption for secure communication.

Permanent Anchors and Adaptive Throughput: Extending Proof‐of‐Access Consensus to Resolve the Blockchain Trilemma

IET Information Security, Volume 2026, Issue 1, 2026.
Contemporary distributed ledgers face an inherent trilemma when attempting to simultaneously optimize three critical properties: transaction throughput (measured in transactions per second [TPS]), network security, and node decentralization. Current decentralized storage platforms such as Filecoin encounter constraints in managing peak transaction ...
