  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.
