Are there any existing, available US type GSM cell phones which provide good end-to-end voice encryption (ie, something better than the broken GSM crypto).
Not to my knowledge. As for European-manufactured phones, the best-known such phone is probably the German Rhode & Schwarz TopSec handset. Rhode & Schwarz is of course the same company that sells a DEM 300,000 IMSI catcher targetted at the domestic German market and an outbound-call-only GSM interception station for "export-only" applications. The customer may wish to take the conflicting interests of the manufacturer into account when making a purchasing decision. The other well-known end-to-end encrypting phone is the Swedish Tiger product initially designed for the Swedish military market. Having participated in architectural discussions with the designers of the device, I would recommend against its purchase. In summary, at present trustworthy end-to-end encrypting GSM handsets are not available in the market place. -- Lucky Green <shamrock@cypherpunks.to> PGP encrypted email preferred.
