Sybil-detection for ad hoc wireless networks


The Mason test is a protocol for detecting Sybil identities in 802.11 ad hoc wireless networks. See our journal publication for a full description.


This code is the prototype implementation of the Mason protocol used for our experiments. It is not feature complete and likely contains security bugs and is intended for research use only.
