  We propose a new security framework for physical layer security (PLS) in the
finite blocklength (FBL) regime that incorporates deception technology,
allowing for active countermeasures against potential eavesdroppers. Using a
symmetric block cipher and power-domain non-orthogonal multiplexing (NOM), our
approach is able to achieve high secured reliability while effectively
deceiving the eavesdropper, and can benefit from increased transmission power.
This work represents a promising direction for future research in PLS with
deception technology.
