Researchers Expose Security Issues in Data Links

Researchers at University at Buffalo were involved in a study exposing possible security vulnerabilities with terahertz data links. These data links play a role in ultra-high-speed wireless data networks of the future. Research showed possibilities for eavesdropping by intercepting a signal from a terahertz transmitter – all without being detected.

Terahertz is a popular option for future wireless networks because it can carry up to 100 times more data than the microwaves used in today’s wireless communication. Terahertz waves travel in narrow, very directional beams, which led to the assumption that the way the waves propagate would naturally enhance security. However, the findings from this recent study prove undetected eavesdropping in the terahertz realm is easier than previously assumed.

The researchers were able to collaborate using NYSERNet’s R&E network.
