Physical Layer: Implement Encryption or Jamming-Resistant Modulation Technique
Data Security at the Physical Layer: A Case Study To study the impact of jamming on secure communication, I will explore the following techniques: Basic Encryption: Simple XOR encryption was used to demonstrate the concept of physical layer security. Jamming Simulation: A specific frequency band was targeted for jamming, mimicking real-world interference scenarios. Frequency Hopping: To counteract jamming, the transmission frequency was dynamically changed. Advanced Encryption: AES-128 encryption was employed to enhance the security of the transmitted data. Modulation: QAM modulation was used to map digital data onto analog signals for transmission. Layered Encryption: A layered approach combining symmetric and asymmetric encryption was investigated to provide robust security. Adaptive Modulation: The modulation scheme was dynamically adjusted to optimize performance based on channel conditions. Error Correction: Hamming codes were used to introduce redundancy into the ...
