A NEW PROPOSED LIGHTWEIGHT CIPHER

Modern cryptography algorithm development has favored hardware optimization in computer systems. This is especially important for fitting cryptographic protocols onto devices with limited computing capacity, volume, and power consumption. Lightweight cryptography is an intellectual pursuit that develops cryptographic methods for economically frugal systems. This study introduces a revolutionary lightweight block cipher based on bio features for adequate cryptographic data security. A carefully planned sequence of analytical paradigms, the core of which involves complex computations to evaluate the proposed cryptographic approach, supports this innovation's theoretical foundations. As detailed in the research, these extensive assessments demonstrate the technology's strong security. The essay examines frequency analysis, frequency within block analysis, and the run test to provide a more complete review. These analytical tools provide sophisticated information regarding the algorithm's resilience to specific cryptographic vulnerabilities. Frequency analysis measures value distribution in the cipher, revealing possible susceptibilities. Frequency within block analysis shows complex value patterns inside discrete blocks, indicating the algorithm's behavior under certain situations. The run test is essential for determining the algorithm's avalanche impact. A careful evaluation of sequential value distribution tests the algorithm's innate sensitivity to input changes, a prerequisite for cryptographic security. This paper carefully examines cryptography algorithmic assessment following academic abstract principles. It includes core security assessments, frequency, frequency within the block, and run tests. The proposed lightweight block cipher's evaluative rigor supports its merit and cogency, making it a significant contribution to the evolving landscape of cryptographic algorithms for resource-constrained computational ecosystems.
