Attacks on A5/1 as used in GSM
[edit]Hello,
The link http://reflextor.com/trac/a51/wiki is dead, it might be a good idea to cite on of the pages linked here instead: https://srlabs.de/decrypting_gsm/ .[Down also- 8/11/2019]
Also, I don't think that the A5/1 Cracking Project was announced at black hat 2009. The schedule can be seen here: https://www.blackhat.com/html/bh-usa-09/bh-usa-09-schedule.html . I think that the first annoucement was at HAR2009: http://www.cs.virginia.edu/~kn5f/pdf/090815.HAR.A51.Cracking.pdf .
