Examining the Practicality of Physical Layer Security
Tyler Sweat
Abstract:
As the amount of devices communicating wirelessly increases, so does the demand for secure and reliable data transfer. The current standard of securing communications is via cryptography, which relies on the mathematical difficulty of a brute force attack. Physical layer security approaches the problem of security from an information theoretic point of view. Previous research has examined the performance that could be achieved by applying the theory to channel sounding measurements taken over SISO channels. Our research expanded this approach to MIMOME (multi-input, multi-output, multi-eavesdropper) channels. Now, our focus is to build out a proof-of-concept SISO system that applies different codes in order to examine the assumptions needed to achieve secure data transmission. Future work will expand this to a MIMO system.
