Network World – If you are ultra paranoid, what could be better than hiding your network traffic in such a way that no one could possibly intercept it? This is what Unisys is offering with its new Stealth appliance, which could make man-in-the-middle attacks and keylogger exploits obsolete, or at least more difficult to mount.

Stealth has been around since 2005, when it was developed exclusively for the Defense Department, which remains one of its largest customers. Several years ago Unisys took it to commercial enterprises and has paid for various independent tests to try to compromise the system, all of which have failed.

This is because Stealth uses four layers of security: each packet is encrypted with AES256, then split into three separate pieces and dispersed across the network, destined for a particular group of users that have to be running its protocols.

To deploy Stealth, you create virtual “communities […]

The potential attacks include: accessing the TV’s configuration files; accessing files stored on USB devices attached to the TV; broadcasting video, audio and images to the TV; controlling the TVs via an external remote control application and stealing website authentication cookies from the TV’s browser.

The insecure network is opened by Miracast, a feature that […]
