Do you think your calls over GSM networks are safe?
That no one listens to your confidential customer calls? Recently the A5/1 code use for GSM call encryption in Europe was hacked within 3 months of being introduced. As a result there is a so-called “rainbow table” sized 2TB which can be used by almost anyone to decode phonecalls. The table is now available on public internet.
Secure your calls with Koolspan TrustVoice
Now you can prevent illegal listening with Koolspan TrustVoice
- KoolSpan’s TrustChip – a fully hardened, self-contained security engine

- Central control, option to remotely disable the chip in case of loss or theft
The solution is a combination of the TrustChip, a simple application in the mobile device and a relay server.
Simply look up your contact in the address book and select “Place Secure Call”. The smartphone will connect to the server, verify authentication and connect the secure call. The voice is converted into a .amr file and encrypted with a 256-bit key. It is then sent as data and decoded by the receiving device.
