numbers for di?®erent hardware components within the device. It consists of
two components, server and client software. The server encrypts and inventories
the digital fingerprint in a database. The client resides on all end-point
devices to establish secure sockets layer (SSL) connections for secure transmission
of the device??™s fingerprint required for hardware authentication. This
approach is intrusive and su?®ers from administrative overhead involved in distributing
the client software and updating the database every time a hardware
component changes in the device. Further, this approach generates tra?±c,
placing additional strain on the wireless link.
Radio frequency (RF) fingerprinting captures the unique characteristics of
the RF energy of a transceiver. When a radio transmitter is placed in transmit
mode, a transient is generated by the frequency synthesizer whose function it is
to generate the carrier frequency used for transmission. It has been determined
that the turn-on transients generated are distinct enough that positive identification
of the transmitter is possible. This technology was originally used
in the cellular industry to identify fraudulent clones [13] .
