=== OP25 Project—Encryption flaws in DES-OFB and ADP ciphers ===

At the Securecomm 2011 conference in London, security researcher Steve Glass presented a paper, written by himself and co-author Matt Ames, that explained how DES-OFB and Motorola's proprietary ADP (RC4 based) ciphers were vulnerable to brute force key recovery.<ref>{{cite web |url=http://securecomm.org/2011/paperlist.shtml |title=SecureComm 2011 7th International ICST Conference on Security and Privacy in Communications Network |access-date=2012-05-15 |url-status=dead |archive-url=https://web.archive.org/web/20120203173219/http://securecomm.org/2011/paperlist.shtml |archive-date=2012-02-03 }} Securecomm 2011</ref> This research was the result of the OP25 project<ref>{{Cite web|url=http://osmocom.org/projects/op25/wiki|title=WikiStart - OP25 - Open Source Mobile Communications|website=osmocom.org}}</ref> which uses [[GNU Radio]]<ref>{{Cite web|url=https://www.gnuradio.org/|title=GNU Radio - The Free & Open Source Radio Ecosystem · GNU Radio|website=GNU Radio}}</ref> and the Ettus [[Universal Software Radio Peripheral]] (USRP)<ref>{{Cite web|url=https://www.ettus.com/|title=Ettus Research - The leader in Software Defined Radio (SDR)|first=Ettus Research, a National Instruments|last=Brand|website=Ettus Research}}</ref> to implement an open source P25 [[packet sniffer]] and analyzer.
