In response to Carmen's request for GSM info ...

GSM is an (originally French) standard for secure, digital, cellular
communications, mainly voice.  Most information is not available
electronically, as the European Technical Standards Institute (ETSI)
makes a lot of money charging for the paper versions. While some info
is available on-line, the detailed recommendations have to be purchased:

ETSI Publications Office
06921 Sophia Antipolis Cedex
France
Fax: +33 92 94 42 58
Tel.: +33 92 94 42 00
There are many documents, each priced at about 3000 ECU!

A postscript version of the basic technical specifications from ETSI is
available by FTP at ftp.dfv.rwth-aachen.de in directory
/pub/doc/cellular/cn/gsm_rec.ps.gz

This is the FTP archive for the Cellular Digest, and much useful (but usually
very technical) material can be found in the pub/doc/cellular/digest direc-
tory.

Various related standards are available at the ITU server, Gopher to
info.itu.ch or http://info.itu.ch and look under Telecommunications
standards / recommendations / Series M [for Mobile] recommendations.
You can also search for keywords, though you won't find much under
'GSM'.

Some discussion of the cryptography and security used in GSM (A5/1)
can be found at the Cypherpunks web archive, http://www.hks.net/cpunks/
index.html, where you can try a keyword search for 'GSM'.

Source code of an implementation of the European GSM 06.10 provisional
standard is available by FTP:
tub.cs.tu-berlin.de/pub/tubmik/gsm-1.0.tar.Z
with gsm-1.0-patch1 and gsm-1.0-patch2 in the same directory.

Another (apparently faster) version is at liasun3.epfl.ch in
/pub/audio/gsm-1.0pl2.tar.Z
