GSM-CRYPTO

EnCrypted Quad-Band GSM Cell Phone

The Problem
Telecommunications interception has developed into a major industry in the last two decades. Intelligence agencies and private organizations within all countries routinely intercept calls that may yield sensitive political, military or economic information.

The use of wiretapping has become so widespread, simple and uncontrolled that you must assume that records of your private calls end up in the wrong hands. Equipment for wireless interception of mobile phone calls has become available at such low prices that it is deployed frequently even in comparatively small business conflicts. So using encryption to protect your privacy is the prudent choice.

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. GSM-Crypto - 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 GSM-Crypto 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 GSM-Crypto enables you to put the trust where it belongs - into a trustworthy, open and scientific verification process.

The GSM-Crypto 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 (See reverse side for technical details).

The GSM-Crypto encrypts your calls with the two algorithms that are regarded strongest by the cryptographic community - AES and Twofish.

The GSM-Crypto is easy to use too. It has a simple interface using a bright and crisp touch-screen with large keys and easy to read display, making it an ideal solution for both less technical inclined users and those with slight vision impairment. The included professional quality headset gives you the option to phone hands free when necessary and to enhance your privacy while phoning in a public place. However, unlike other products, the GSM-Crypto does not require the headset for operation.

The GSM-Crypto hardware is based on a standard GSM equipped phone. So you can buy accessories on the open market at normal price from your normal retailer channels. Since the GSM-Crypto device is not distinguishable from the normal hardware it is based on, you will not get suspicious looks at the airport or border control. You enjoy your privacy - in private.
