Defence boffins show off novel online security device

The Defence Science and Technology Group have developed a new device that allows internet transactions and content to be secured when using untrusted computing infrastructure.

The Digital Video Guard (DVG) is designed to decrypt, verify and display content independent of the computing infrastructure being used.

When installed between a host computer and and external display, the DVG allows the contents of a video signal to be verified. It displays a trust notification via an integrated LED to indicate that the integrity and confidentiality of the displayed information are intact.

Although it has been developed for defence applications, the system has potential applications in securing content delivered over untrusted networks for the banking, finance and medical industries.

Addressing the biggest threats to internet banking, the DVG can protect against keystroke loggers and phishing attacks involving redirecting users to fake logon screens.

The DVG can also be used to secure email and instant messaging content by sending an encrypted image within a normal message.

The device can be adapted to operate in desktop and laptop environments or be embedded directly into tablet devices. It does not require any client software or drivers to be installed on the host machine.

The scientists who designed the DVG won South Australia’s Research and Development iAward for innovation in ICT in 2014.
