Abstract
This study addresses the critical issue of ensuring data security and efficiency in interconnected devices, especially in IoT environments. The objective is to design and implement a model using cryptographic algorithms to enhance data security in 5G networks. Challenges arise from the limited computational capabilities of IoT devices, which require the analysis and selection of cryptographic algorithms to achieve efficient data transmission. This study proposes a model that includes four levels of security, each employing different levels of encryption to provide better data security. Finally, cloud computing optimizes processing efficiency and resource utilization to improve data transmission.
