• Network congestion

• Data encryption

Explain the concept of electromagnetic interference in the context of IoT physical layer security.

• Electromagnetic interference only affects the software layer of IoT devices.

• Electromagnetic interference enhances the security of the physical layer in IoT devices.

• Electromagnetic interference has no impact on the communication between IoT devices.

• Electromagnetic interference can disrupt the communication between IoT devices and compromise the security of the physical layer.

How can the use of secure hardware modules help in mitigating physical layer threats in IoT?

• By not implementing any security measures at the physical layer

• By providing tamper resistance and secure storage for cryptographic keys.

• By relying on open source software for security

• By using outdated and easily hackable hardware

Discuss the role of encryption in securing the physical layer of IoT devices.

• Encryption only protects the data stored on IoT devices, not the data transmitted over the network

• Encryption has no impact on securing the physical layer of IoT devices

• Encryption helps in securing the physical layer of IoT devices by protecting data transmitted over the network.

• Encryption makes IoT devices more vulnerable to physical attacks

What are the challenges in implementing secure communication protocols at the physical layer of IoT devices?

• Limited resources, vulnerability to physical attacks, and difficulty in ensuring secure key management

• Easy implementation, immunity to physical attacks, and secure key management

• Limited resources, immunity to physical attacks, and easy key management
