Telecommunication Interception
Over the past two decades, telecommunications interception has developed into a major industry. Intelligence agencies and private organizations around the world 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.

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

CryptoPhone is the first secure phone that comes with full source code available for independent review. Finally, you can perform an independent assessment to ensure that there is no weak encryption and no backdoors in the device you entrust your telecommunications security to.
