In this paper, we introduce GTID, a technique that can actively and passively fingerprint
wireless devices and their types using wire-side observations in a local network. GTID …

Node forgery or impersonation, in which legitimate cryptographic credentials are captured
by an adversary, constitutes one major security threat facing wireless networks. The fact that …
