LED and PHOTON are new ultra-lightweight cryptographic algorithms aiming at resourceconstrained
devices. In this article, we describe three different hardware architectures of the LED and
PHOTON fam...
In this paper we present known-plaintext single-key and chosenkey
attacks on round-reduced LED-64 and LED-128. We show that with
an application of the recently proposed slidex attacks [7], one immed...
Bitsliced Implementations of the PRINCE, LED and RECTANGLE Block Ciphers on AVR 8-bit Microcontrollers
PRINCE LED RECTANGLE bitslice block cipher
2015/12/21
Due to the demand for low-cost cryptosystems from industry, there spring up a lot of lightweight
block ciphers which are excellent for some different implementation features. An innovative design is ...
Improved Linear Sieving Techniques with Applications to Step-Reduced LED-64

In this paper, we describe new techniques in meet-in-the-middle attacks. Our basic technique is called a \emph{linear key sieve} since it exploits as filtering conditions linear dependencies between k...
Key Recovery Attacks on 3-round Even-Mansour, 8-step LED-128, and Full $\mbox{AES}^{2}$
secret-key cryptography
2014/3/12
The Even-Mansour (EM) encryption scheme received a lot of attention in the last couple of years due to its exceptional simplicity and tight security proofs. The original $1$-round construction was nat...
