MIT researchers invent tiny cryptographic ID tag

21/02/2020
Researchers at MIT have developed a cryptographic ID tag for combatting supply chain counterfeiting and verifying the authenticity of a product — and it’s small enough to fit on nearly anything.

Presenting the invention at the IEEE International Solid-State Circuits Conference (ISSCC), MIT News reported, the researchers explained how the ID chip addresses common problems of other tagging methods. (RFID tags, they point out, can’t fit on tiny objects such as medical components or silicon chips, nor do they offer rigid security measures.) 

The MIT tag is said to be millimetre-sized and runs on relatively low levels of power, which is supplied by photovoltaic diodes. MIT News said it also “transmits data at far ranges, using a power-free ‘backscatter’ technique that operates at a frequency hundreds of times higher than RFIDs”. Algorithm optimisation techniques allow the chip to run a cryptography scheme to ensure secure communications while using very little energy.
