Description

Research Topic Description, including Problem Statement:

Current networks need to send large amounts of data efficiently and securely between multiple different points. Many methods for implementing physical layer security are inefficient, have difficulty in the presence of multipath and fading channels and/or lack the ability to be implemented for multiple users having simultaneous access.

The goal of this topic is to explore and characterize the performance of physical layer security techniques especially in the presence of multipath and fading channels. The preference is for techniques that primarily utilize physics based approaches to improve security while keeping the links backwards compatible; however, novel approaches that utilize some communications information will be considered. The goal is to design an efficient modern communications system that can incorporate physical security techniques to increase the cost to eavesdroppers to intercept the signal. Characterizing any novel physical layer security needs to address this problem and will involve evaluating system efficiency as well as probability of detection and probability of interception both with and without a priori knowledge.

For any physical layer security technique, practical implementation should be considered including the impact of antenna element choice, array design, protocols, and data rates on error rates, mutual information and multi-user support. The report should also address the tradeoffs for power and system complexity versus the secrecy achieved by the link.

Example Approaches:

Security-oriented beamforming; artificial noise injection; directional modulation; orbital angular momentum (generates the illusion of higher order rotation in the EM field by superimposing phased contributions from an array of antenna elements) Secure Antenna Polarization Modulation (SAPM) (dual polarized antennas are used to create data distortion with an element of randomness at all transmission angles except the intended ones)

Relevance to the Intelligence Community:

  • Increased security and privacy for a variety of communications networks
  • Increased efficiency and reliability of networks using physical layer security techniques

Key Words: Wireless Communications, Physical Layer Security, Cybersecurity, Antenna Arrays
