Cryptanalysis: Theory Versus Practice
IACR Transactions on Symmetric CryptologyMost 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 ...

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.

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.

FPGA BASED HARDWARE KEY FOR TEMPORAL ENCRYPTION [PDF]
ICTACT Journal on Communication Technology, 2010 In this paper, a novel encryption scheme with time based key technique on an FPGA is presented. Time based key technique ensures right key to be entered at right time and hence, vulnerability of encryption through brute force attack is eliminated ...

IACR Transactions on Symmetric CryptologyThe impossible differential (ID) attack is one of the most important cryptanalytic techniques for block ciphers. There are two phases to finding an ID attack: searching for the distinguisher and building a key recovery upon it.

Impossible Differential Cryptanalysis of 16/18-Round Khudra
, 2017 Khudra is a recently proposed lightweight block cipher specifically dedicated for Field Programmable Gate Arrays (FPGAs) implementation. It is a 4-branch type-2 generalized Feistel structure (GFS) of 18 rounds with 64-bit block size and 80-bit security margin. This paper studies the security of Khudra against impossible differential cryptanalysis.
