Swiss Video On Mobile Telephone Security

This is an informative video from the Swiss boob tube plan Einstein, almost the potential threats as well as risks of mobile jail cellphone phones:

The telephone shown inwards this study is the Secure Mobile Phone Omnisec 230 (fact canvas inwards PDF), made past times the Swiss theatre Omnisec AG. This is a modified HTC smart phone, with a hardened Android operating system, as well as with all direct a opportunity providing applications (like bluetooth as well as GPS) removed. The microSD Security Module provides encryption with 256-bits cardinal length to secure communication for classification levels upwardly to Top Secret. But, the damage for ii of such phones is said to endure unopen to 50.000,- Swiss Franks.

UMTS

For most people, a far to a greater extent than affordable manner to teach amend safety for jail cellphone telephone communication is but to run the UMTS or 3G mobile network, instead of GSM. Where GSM entirely has authentication of the user to the network, UMTS uses usual authentication, which agency the mobile user as well as the network authenticate each other. This prevents a thus called "man-in-the-middle attack" past times using imitation base of operations stations. Also UMTS uses stronger encryption algorithms (KASUMI-based 128-bit cardinal algorithms) for securing the phonation as well as information during the radio transmission betwixt the handset as well as the base of operations station. For this, GSM uses the rather weak A5/1 algorithm with entirely a 64-bit key.

Nowadays, UMTS services are widely available inwards western countries as well as accessible through high-end smart phones similar the pop iPhone 3G as well as the Samsung Milky Way i9000 series. However, it should endure noted that the run of the UMTS-network nevertheless deportment the risks of intrusions through dangerous applications as well as malware. Furthermore, UMTS does non render whatever end-to-end encryption or authentication betwixt 1 user as well as the other. Traffic betwixt between the fixed network stations is nevertheless unencrypted as well as there's authentication entirely betwixt users as well as the network provider.

BlackBerry

Another affordable alternative for to a greater extent than secure mobile communication is past times using the BlackBerry smart phone, which is real pop with trouble organization people as well as authorities officials. Influenza A virus subtype H5N1 BlackBerry UK, Canada as well as Australia. But again: this entirely applies to email messages as well as non for phonation conversations.

So, people who desire or take the certainty of strictly individual telephone calls from 1 somebody to another, convey to assure that through extra applications or specialized hardware features, for representative similar the aforementioned Omnisec telephone or a diversity of other highly secure mobile phones.
