        abstract = {In the era of cloud computing and IoT, securing data through encryption is crucial to prevent unauthorized access and protect sensitive information. This study proposes a novel approach to key generation using a 3D chaotic system within a hybrid lightweight encryption algorithm tailored for IoT-based cloud security. The encryption technique combines the Lightweight Encryption Algorithm (LEA) and Advanced Encryption Standard (AES) to create a robust defense mechanism for critical data. Enhancements such as AES S-box, Shift Rows, Mix Columns, and Add Round Key have been integrated into the Z-LEA algorithm, increasing the complexity of the encrypted data and minimizing the risk of unauthorized decryption. The 3D chaotic system plays a key role in generating highly secure, nonlinear, and dynamic keys. Additionally, the proposed system reduces both the number of encryptions rounds and execution time (encryption/decryption) by implementing parallel processing techniques. Experimental results demonstrate that the Z-LEA encryption system is resistant to various attack vectors, significantly reduces computation time, and generates a highly random key stream, validated through the NIST randomness test.},
