At Crypto 2015, Blondeau, Peyrin and Wang proposed a truncated-differential-based known-key attack on full PRESENT, a nibble oriented lightweight blockcipher with a SPN structure. The truncated difference they used is derived from the existing multidimensional linear characteristics. An innovative technique of their work is the design of a MITM layer added before the characteristic that covers ...

RECTANGLE is a newly proposed lightweight block cipher which allows fast implementations for multiple platforms by using bitslice techniques. It is an iterative 25-round SPN block cipher with a 64-bit block size and a 80-bit or 128-bit key size. Until now, the results on analyzing the cipher are not too much, which includes an attack on the 18-round reduced version proposed by the designers the...

In eSTREAM project, a few lightweight stream cipher for hardware was introduced (2008) and then in FSE 2015 Sprout was proposed. Sprout introduced a new idea, design of stream cipher with shorter internal state by using key not only in initialization but also in keystream generation, but it was insecure. Grain-v1 is almost the lightest secure cipher in world. Fruit stream cipher is successor of...

In this paper we introduce FELICS, a free and open-source benchmarking framework designed for fair and consistent evaluation of software implementations of lightweight cryptographic primitives for embedded devices. The framework is very flexible thanks to its modular structure, which allows for an easy integration of new metrics, target devices and evaluation scenarios. It consists of two modul...

With the development of Internet Things (IoT) technology, IoT devices are integrated into many our daily lives, including industrial, security, medical, and personal applications. Many violations safety have appeared due to critical physical infrastructure, network vulnerabilities. Considering nature restricted limited resources these in terms size, capacity, energy, Security is becoming increa...

in this paper, we show how to obtain suitable differential charactristics for block ciphers with neural networks. we represent the operations of a block cipher, regarding their differential characteristics, through a directed weighted graph. in this way, the problem of finding the best differential characteristic for a block cipher reduces to the problem of finding the minimum-weight multi-path...

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 family optimized for Field-Programmable Gate Array (FPGA) devices. In the first architecture we propose a round-based implementation while the second is a fully serialized architecture performing operat...
