Physical Layer: Implement Encryption or Jamming-Resistant Modulation Technique

By - on
Image
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 ...

Physical Layer: Frequency Hopping Spread Spectrum (FHSS) Simulation

By - on
Image
Introduction to Frequency Hopping Spread Spectrum Frequency Hopping Spread Spectrum (FHSS) is a wireless communication technique where the transmitter and receiver synchronously switch (or "hop") between multiple frequency channels according to a predetermined pattern. This method provides three key advantages: Anti-jamming protection : By rapidly changing frequencies, only a portion of the transmission is affected by narrowband jamming. Security : The hopping pattern acts as an additional layer of encryption Coexistence : Multiple networks can operate in the same band with minimal interference T his tutorial explores a Python simulation that demonstrates FHSS with encryption and error correction, providing insights into the mathematical foundations of secure wireless communication. 1. Frequency Hopping Model The core FHSS transmission can be modeled as: s(t) = A·cos(2ฯ€fโ‚™t + ฯ•)·d(t) Where: fโ‚™ ∈ {f₁,f₂,...f_N}  is the hopping frequency at time t d(t) ∈ {0,1}  is the digital da...
