ADELPHI, Md. — Army researchers have been awarded a patent for inventing a practical method for Army wireless devices to covertly authenticate and communicate.
Authentication is one of the core pillars of wireless communications security, along with secrecy and privacy. The value of authentication in a military setting is readily apparent and mandatory.
Receivers verify that an incoming transmission did indeed come from an ally and not a malicious adversary, therefore maintaining the integrity of communications. This invention, in particular, greatly increases an adversary’s difficulty in impersonating an ally.
