CP-ABE serves as a powerful cryptographic approach, allowing controlled data access through encryption policies. This makes it highly applicable in domains such as the Internet of Things, cloud computing, and secure information sharing. However, the initial CP-ABE scheme often suffers from inefficiencies in several phases and outdated security levels. To overcome these challenges, we introduced a CP-ABE construction leveraging ELiPS, enhancing the security level to 128 bits and improving computational performance. Furthermore, this work, we evaluate the proposed scheme on both server and practical IoT environments. Our results show that our scheme significantly improves performance, reducing the setup, key generation, and encryption times by 22.6%, 74.4%, and 42.1%, respectively. Although the proposed scheme increases security to 128 bits, it does not significantly increase ciphertext size and even reduces average memory usage by 12.4%. The findings from our experiments demonstrate that the introduced scheme achieves high efficiency and is suitable for applications requiring strong security on both general-purpose systems and resource-constrained platforms.
