Pocket PC Phone Edition with encryption voice calls capabilities
Are you paranoid with Echelon listening to your mobile phone calls? Or you have a real reason to be careful? The CryptoPhone is a GSM mobile phone that provides security against anyone listening into your calls. To set up a secure call, both parties need to use a CryptoPhone.

The GSMK CryptoPhone claims to be the first product using the fact that the CPU performance of consumer devices, like mobile phones and PDAs, is now sufficient for strong real-time voice encryption.

The company says "The current version of the CryptoPhone runs on top of a heavily modified and stripped down Microsoft PocketPC2002 ROM. The reason is that we wanted an affordable and well researched platform that offered sufficient performance for the speech encoding and crypto functions.A Pocket PC based system was chosen as the first platform for CryptoPhone because it was the only sufficiently fast device allowed us to do software integrity protection in ROM and the stripping of unnecessary functions."

Exports of the GSMK CryptoPhone products to other EU countries have no restrictions. Export to Australia, Japan, Canada, New Zealand, Norway, Poland, Switzerland, Czech Republic, Hungary, and the United States of America are also unrestricted. Information requirements are the same as for EU countries.
