Physical layer security in Body Area Network using spread spectrum communication.

What is it about?

My article will contribute security in Wireless Body Area Network. Implementation of Wireless Body Area Network (WBAN) plays an important role in the security of physiological data (e.g. ECG, EEG etc.). But on practical implementation, this WBAN faces physical layer attacks such as jamming and eavesdropping. Thus, in order to counteract jamming and eavesdropping, spread spectrum techniques such as Direct Sequence Spread Spectrum (DSSS) and Frequency Hop Spread Spectrum (FHSS) have been commonly adopted. The vulnerability in conventional SS is the requirement of pre-shared key between sender and receiver.So to overcome the problem of pre-shared keys and to enhance the security of WBAN, the Chaotic Frequency Hopping Spread Spectrum (CFHSS) has been proposed in this work.

Why is it important?

Chaotic Frequency Hopping Spread Spectrum (CFHSS) provides physical layer security against physical layer attacks such as jamming and eavesdropping.
