Abstract
As the Internet of Things (IoT) continues to expand, ensuring secure and efficient data
storage and retrieval becomes a critical challenge. IoT devices, often constrained by limited
computational resources, require lightweight encryption protocols that balance security and
performance. This paper presents an optimized encryption protocol designed specifically for
lightweight, searchable data in IoT environments. The proposed protocol utilizes advanced
optimization techniques to enhance the efficiency and security of searchable encryption,
enabling rapid data retrieval without compromising the integrity and confidentiality of the data.
The protocol leverages a hybrid cryptographic approach, combining symmetric and asymmetric
encryption, to ensure robust protection against unauthorized access while maintaining low
computational overhead.
