Lightweight cryptographic algorithms are critical for safeguarding resource-constrained contexts like IoT devices, RFID systems, and embedded software. This approach is intended to provide robust security while requiring minimal computing overhead, assuring efficiency in power-limited systems. The NYKS lightweight cryptographic technique is constructed and assessed using comprehensive security and performance measures to determine its applicability for such contexts. Security is evaluated using the Avalanche Effect, which takes into account non-linearity, confusion, diffusion rates, linear closeness, and Hamming distance to ensure resistance to cryptanalysis. Efficiency is determined by comparing encryption speed and throughput to computational efficiency. Experimental results show that NYKS has a greater Avalanche Effect (53%) than PRESENT (51%), Improved PRESENT (52%), and TWINE (50%), indicating superior diffusion features that improve cryptographic security. Additionally, NYKS exceeds its predecessors in efficiency, achieving an encryption speed of 100 ns, which is much quicker than PRESENT (310 ns), Improved PRESENT (310 ns), and TWINE (360 ns). Furthermore, NYKS has the maximum throughput at 640 Mbps, making it an excellent choice for high-speed, low-power applications, particularly in battery-constrained IoT devices and RFID systems.
