Description: Lightweight security refers to a set of security measures designed to be efficient and have a minimal impact on the performance of devices and systems, especially in the context of Internet of Things (IoT) and other resource-constrained environments. This approach seeks to balance the need to protect data and infrastructure with the resource limitations that such devices often present, which may have reduced processing and storage capabilities. The main characteristics of lightweight security include the implementation of optimized encryption algorithms, simplified authentication, and the use of communication protocols that minimize overhead. The relevance of lightweight security lies in its ability to allow devices to operate securely without compromising their functionality or efficiency. As the number of connected devices continues to grow, lightweight security becomes an essential solution to protect data integrity and user privacy while ensuring optimal performance.
