N2 - In this work, we derive the secrecy degrees of freedom (s.d.o.f.) region of the Gaussian two-way wiretap channel in which the eavesdropper channel state is arbitrarily varying and is unknown to the legitimate nodes. We prove that the s.d.o.f. region is identical to that when the eavesdropper channel is fixed and globally known. A multi-stage coding scheme that combines secret key generation and confidential message transmission is developed to prove achievability. The confidentiality guarantee provided in this work is in the sense of strong secrecy.
