Area of Science:

• Computer Science
• Electrical Engineering
• Cybersecurity

Background:

• Internet of Things (IoT) devices have limited resources, making classical cryptography unsuitable.
• Physical layer security offers a more efficient alternative by leveraging channel characteristics.

Purpose of the Study:
