The Simon and Speck families of block ciphers were designed specifically to offer security
on constrained devices, where simplicity of design is crucial. However, the intended use …

Two lightweight block cipher families, Simon and Speck, have been proposed by
researchers from the NSA recently. In this paper, we introduce Simeck, a new family of …

Abstract The US National Security Agency (NSA) developed the SIMON and SPECK families
of lightweight block ciphers as an aid for securing applications in very constrained …

In this paper we analyse the general class of functions underlying the Simon block cipher. In
particular, we derive efficiently computable and easily implementable expressions for the …

Multimedia communication is revolutionizing all major spheres of human life. The advent of
IoT and its applications in many fields like sensing, healthcare and industry, result …

In the present paper, we propose an automatic search algorithm for optimal differential trails
in SIMON-like ciphers. First, we give a more accurate upper bound on the differential …

Simon and Simeck are two lightweight block ciphers with a simple round function using only
word rotations and a bit-wise AND operation. Previous work has shown a strong clustering …

Simon is a lightweight block cipher family proposed by NSA in 2013. It has drawn many
cryptanalysts' attention and varieties of cryptanalysis results have been published, including …

The study of lightweight block ciphers has been a “hot topic”. As one of the main structures of
block ciphers, the Feistel structure has attracted much attention. However, the traditional …

Simeck is a new lightweight block cipher design based on combining the design principles
of the Simon and Speck block cipher. While the design allows a smaller and more efficient …
