Abstract:
This paper presents the application of specific emitter
identification (SEI) to access control and points out the security
caveats of current radio-based access remotes. Specifically,
SEI is applied to radio frequency (RF) access remotes used to
open and close motorised gates in residential housing complexes
for the purposes of access control. A proof-of-concept SEI system
was developed to investigate whether it is possible to distinguish
between the RF signals produced by two nominally-identical
access remotes. It was determined that it is possible to distinguish
between the remotes with an accuracy of 98%.
