Encryption as you have never seen it before: CryptoPhone - a Pocket PC phone with voice encryption
November 18, 2003 [Pocket PC phone] | By anonymous 1.

Not everybody knows that with an equipment of value around $10000 one can eavesdrop GSM phone calls in real time. Apart from that several carriers are obliged to provide unencrypted access to phone calls of customers to various security agencies. But sometimes, particularly during carrying out of bigger business deals, privacy of phone calls is very important. This is where CryptoPhone cames into play:

Gizmodo - the United Kingdom of gadgets writes (text in italics):

Really worried about eavesdroppers? German company Cryptophone is selling a special version of HTC´s XDA Pocket PC Phone that comes complete with built-in encryption technology that makes it next-to-impossible for anyone to intercept and listen in on your phone calls.

The catch is that only the phone can only make secure calls to another XDA or a PC with the same software installed on it (it can make regular calls to anyone). CryptoPhone is selling a pair of the phones for 3,499 euros, so you have to really value your privacy.

Here are some features of Cryptophone 100:
  • ensuring your voice´s privacy
  • Strongest and most secure algorithms available today
  • AES256 and Twofish
  • 4096 bit Diffie-Hellman key exchange with SHA256 hash function
  • Readout-hash based key authentication
  • 256 bit effective key length
  • encryption key is destroyed as soon as the call ends
  • Source code available online for independent security assessments
  • also supports unencrypted calls, unencrypted SMS, address book, calendar etc.
  • works in any 900/1800 GSM network that provides data call facilities
  • Standby: 150 hours
  • Talk time: Secure up to 3 hours 15 minutes / Unsecured up to 3 hours 30 minutes
