But protecting your information with strong and trustworthy encryption has become difficult. "Proprietary" or "Secret" algorithms of dubious quality, and encryption that is too weak to protect against modern computing power are commonplace in the telecommunications market. These weaknesses are masked by marketing efforts, suggesting that you need to rely on "the secrecy of the algorithm" or "government classification" - certified by the same intelligence agencies that are actually in charge of telecommunications interception.

Now there is a solution that you can trust, because it can be verified by you or by your experts. GSMK CryptoPhone, the first secure mobile phone that comes with full source code available for independent review - is available now. Finally, you can perform a independent assessment to ensure that there is no weak encryption and no backdoors in the device you entrust your telecommunications security to. You don't have to believe us when we say it is secure - you can verify that claim yourself.

The GSMK CryptoPhone is not a black-box-device with scarce technical information, like other products in the market. We will give you all the details of its inner workings - even before you buy. The GSMK CryptoPhone Enables you to put the trust where it belongs - into a trustworthy, open and scientific verification process.

The GSMK CryptoPhone technology is based on well-researched algorithms for both encryption and voice processing, the strongest encryption available combined with key length that provides peace of mind today and in the future. The GSMK CryptoPhone encrypts your calls with the two algorithms that are regarded strongest by the cryptographic community - AES and Twofish.

GSMK is a company located in Berlin, Germany that builds the first mobile phone that provides strong end-to-end voice encryption with full source code published for review.

The GSMK CryptoPhone is the first product using the fact that the CPU performance of portable consumer devices, like mobile phones and PDAs, is now sufficient for strong real-time voice encryption. The processing power available today in every pocket makes it finally possible to effectively counter the rampant telecommunications surveillance.

Strong, verifiable and trustworthy voice encryption in every mobile smart phone and PDA will be as common as IPSec is today in even the cheapest DSL router boxes. The progress of technology finally provides the individual with the necessary means to take care of its privacy rights. Widespread wiretapping and privacy violations are currently threatening the business environment, civil liberties and the very future of democratic societies.

There seems to be no realistic way to stem by political process alone the current flood of intrusive communication surveillance. Now the technical means for strong cryptographic protection of voice privacy are available also to the not technical inclined users.
The GSMK CryptoPhone is strong telephony encryption for the rest of us.
