Supplementary file 1_Efficient lightweight cryptographic solutions for enhancing data security in healthcare systems based on IoT.zip حسب Abdul Muhammed Rasheed (20998115)

"…This study presents three efficient cryptographic methods: (1) a hybrid encryption algorithm that incorporates a Fibonacci sequence and a 6D hyper-chaotic system to improve confusion and diffusion; (2) hybrid lightweight encryption that utilizes logistic parity-based chaotic maps for secure data transformation; and (3) combined transformation and expansion (CTE)-based lightweight cryptography that employs dynamic chaotic systems for strong encryption. …"
