Secure Cell Phone - GSMK
GSMK CryptoPhone 200 Trustworthy Voice Encryption
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 Problem
All telecommunication networks worldwide are subject
to routine call interception. 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.
Today’s Solution
Now there is a solution that you can trust, because it
can be verified by you or by your experts. The GSMK
CryptoPhone 200, the first secure Tri-Band 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 200 enables you to put the
trust where it belongs – into a trustworthy, open and
scientific verification process.
The GSMK CryptoPhone technology is based on wellresearched
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 GSMK CryptoPhone encrypts your calls with the
two algorithms that are regarded strongest by the
cryptographic community – AES and Twofish.
Ease of use
The GSMK CryptoPhone 200 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
handsfree when necessary and to enhance your privacy
while phoning in a public place. However, unlike other
products, the GSMK CryptoPhone 200 does not require
the headset for operation.
The GSMK CryptoPhone 200 hardware is based on a
standard GSM equipped PDA-phone. So you can buy
accessories on the open market at normal price from
your normal retailer channels. Since the GSMK CryptoPhone
200 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.
Landline and satellite telephony solutions
for secure communication from a standard analog
(POTS) or ISDN landline with a mobile GSMK Crypto-
Phone user, you can choose between a dedicated
Desktop GSMK CryptoPhone device or the free GSMK
CryptoPhone for Windows software. The Desktop GSMK
CryptoPhone offers secure communication to other
landline, mobile and satellite GSMK CryptoPhone
products.1) The free GSMK CryptoPhone for Windows
software is an excellent way to establish secure communication
with partners who do not yet own a GSMK
CryptoPhone device. GSMK CryptoPhone Satellite
Solutions are perfect for use in areas with bad or no
mobile phone coverage. GSMK CryptoPhone Satellite
Solutions are becoming available for a number of
different satellite systems, such as Thuraya, Globalstar
and certain Inmarsat modes. (Please contact us for
detailed availability information)
All GSMK CryptoPhone devices and solutions use the
same encryption, are fully interoperable and offer the
same level of protection against interception across
communication networks.
