The cube attack extracts the information of secret key bits by recovering the coefficient called
superpoly in the output bit with respect to a subset of plaintexts/IV, which is called a cube …

The advancement in cryptographic algorithms is the primary need for modern secure
communication systems. In secure communication system, the stream cipher serves the …

In stream cipher designing, nonsingularity is a crucial requirement to ensure that the
feedback shift registers (FSRs) do not produce keys that are equivalent to one another. This …

In resource-intensive Internet of Things applications, Lightweight Stream Ciphers (LWSCs)
play a vital role in influencing both the security and performance of the system. Numerous …

We present the first comprehensive approach for detecting and analyzing symmetric
cryptographic primitives in gate-level descriptions of hardware. To capture both ASICs and …

The increasing complexity of system-on-chip (SoC) designs, prompted by the integration of
additional functionalities, has led to a reliance on global sources in the SoC supply chain …

A transciphering framework, also known as hybrid homomorphic encryption, is a practical
method of combining a homomorphic encryption~(HE) scheme with a symmetric cipher in …

Abstract Today, the Internet of Things (IoT) and its devices can be found everywhere and
send massive quantities of data, and scientists expect that people will increasingly rely on …

Nonlinear feedback shift registers (NFSRs) are used in many stream ciphers as their main
building blocks. In particular, Galois NFSRs with terminal bits are used in typical stream …

This chapter presents an overview of the design approaches to stream ciphers. It starts with
defining the scope and presenting generic constructions as well as attacks based on these …
