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 ...

Cryptanalysis of QARMAv2

IACR Transactions on Symmetric Cryptology
QARMAv2 is a general-purpose and hardware-oriented family of lightweight tweakable block ciphers (TBCs) introduced in ToSC 2023. QARMAv2, as a redesign of QARMAv1 with a longer tweak and tighter security margins, is also designed to be suitable for ...

Finding Complete Impossible Differential Attacks on AndRX Ciphers and Efficient Distinguishers for ARX Designs

IACR Transactions on Symmetric Cryptology
The 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.
