Subjects:	Stream ciphers, Shift registers, Internet of things, Cryptography, Logic circuits, Computer performance, Field programmable gate arrays
Abstract:	The purpose of ubiquitous computing is to smoothly incorporate intelligent gadgets into typical environments. Lightweight cryptographic solutions are becoming more and more necessary since these devices are resource-constrained and cost-sensitive. Stream ciphers (SCs) are similarly important in pervasive computing, especially for secure communication in network streams where plaintext sizes may fluctuate dynamically, even if block ciphers (BCs) have proven to perform well in symmetric-key encryption. A thorough analysis of stream cipher systems based on Linear Feedback Shift Registers (LFSRs) and Nonlinear Feedback Shift Registers (NFSRs) is presented in this study. Field Programmable Gate Array (FPGA) implementations are used to do a thorough comparative investigation of important performance measures, such as area, latency, throughput, and efficiency. The article also explores future approaches for stream cipher optimization based on LFSR and NFSR in lightweight and resource-constrained IoT contexts, highlighting current research trends.

Abstract:	The purpose of ubiquitous computing is to smoothly incorporate intelligent gadgets into typical environments. Lightweight cryptographic solutions are becoming more and more necessary since these devices are resource-constrained and cost-sensitive. Stream ciphers (SCs) are similarly important in pervasive computing, especially for secure communication in network streams where plaintext sizes may fluctuate dynamically, even if block ciphers (BCs) have proven to perform well in symmetric-key encryption. A thorough analysis of stream cipher systems based on Linear Feedback Shift Registers (LFSRs) and Nonlinear Feedback Shift Registers (NFSRs) is presented in this study. Field Programmable Gate Array (FPGA) implementations are used to do a thorough comparative investigation of important performance measures, such as area, latency, throughput, and efficiency.
