Max :), Now it is time for some RAKEs and OOK-based weaknesses in O-CDMA. Wondering when it all happens, I mean, when we come up with (enough) good solutions for the eavesdropping on mobile networking. It is, however, much much more complicated than current research works available (frequency hopping and various other techniques used). For instance (to be more precise), Ryu and Jang in "A Security Weakness of the CDMA(Code Division Multiple Access)Cellular Service" noted that FCM protocol might allow CDMA eavesdropping etc. Or, what about anti-symmetric grating suggested by Castro and Geraghty used (to some extent also, although not only!) for security purposes? As I said, plenty of opportunities to work on in this field. I have, for instance, worked recently very much on UMTS security issues. Nevertheless, nice work, guys. By the way, did you had to build any hardware, or did you use the available? (sorry if I missed that - what i mean is the radio receiver) And the other question or suggestion - one might take a simple follow-the-line robot with the ability to communicate and eavesdrop a little bit on such communication ;-) Cheers! By the way, my conference talk during IT Underground (about the vulnerability research) is available here: http://eleytt.com/research.html Michal
