Query: Enhancing Channel Shortening Based Physical Layer Security Using
  Coordinated Multipoint   Wireless networks have become imperative in all areas of human life. As such,
one of the most critical concerns in next-generation networks is ensuring the
security and privacy of user data/communication. Cryptography has been
conventionally used to tackle this, but it may not be scalable (in terms of key
exchange and management) with the increasingly heterogeneous network
deployments. Physical layer security (PLS) provides a promising alternative,
but struggles when an attacker boasts a better wireless channel as compared to
the legitimate user. This work leverages the coordinated multipoint concept and
its distributed transmission points, in conjunction with channel shortening, to
address this problem. Results show significant degradation of the
bit-error-rate experienced at the eavesdropper as compared to state-of-the-art
channel shortening-based PLS methods.
