The research group Low Power Design, Test, Verification and Integrated Circuits for Security (QINE) at the UPC has worked to develop a cybersafe hardware system for  the identification of integrated circuits and for new generation memory devices.

The project has been developed using prototypes of memristors, new generation memory devices that can store in a specific area ten times more information than current flash memories.

In the project, hardware strategies are proposed and analysed to detect and avoid the effects of external attacks on integrated circuits. Taking advantage of the natural variability of the device, unique digital fingerprints are implemented for each of the integrated circuits, which are hard to copy as a result. In addition, safe memory cells are proposed to restrict information leakage.

These studies were part of a three-year project (2015–2018) and received funding of 122,815 euros from the Spanish Ministry of Economy and Competitiveness.
