  1. Security fingerprints for smart physical and digital identities Giacomo BENVENUTI, PhD CERN Workshop, 07/11/2017

  2. Challenge: towards a smart 4.0 era MANUFACTURING 4.0 SMART GRIDS MOBILITY 4.0 3D-PRINTING INSURETECH IoT & IIoT SMART CITIES SMART SERVICES FINTECH SUPPLY CHAINS BLOCKCHAIN + AI The 4th industrial revolution is here! Smart, Reliable & Intelligent objects.

  3. Pains and hopes… Strong issues: Growing counterfeiting Weak cyber-security Poor traceability of objects and data Lack of trust and value managementBlockchains approachReinforced trust Improved interactions between: ≠ verticals ≠ partnersBut still too many technical intrinsic limits…

  4. Physical and digital FINGERPRINTS Identities to make object SMART! Single object identities Mass Production Physical + Digital solution Strong miniaturization Affordable costs Experimental vs model

  5. Our expertise. Micro and nano 3D and 4D-printing of multifunctional thin films materials

  6. Thin films FUNCTIONALITY2 FUNCTIONALITY 1 PROPERTY 2 PROPERTY 1 + PATTERNING 2 + PATTERNING 1 + LAYER 2 + LAYER 1 SUBSTRATE A high-tech paint with dimensions of 10 nm to 10 mm allowing: • Miniaturization of devices • Development of new material properties due to nano-size effects • Integration of new functionalities (value) onto a substrate HIGH ADDED VALUE More (functionalities / value / quality of life) with less(resources / eco-impact ) = Sustainability

  7. Markets & Applications of thin films PERVASIVE COST EFFECTIVE MASS PRODUCTION Less Resources, Robust devices, Transportability

  8. R&D Network

  9. Our additive growth set-ups Stencil-mask assisted deposition Deposition on patterned substrates 3 Laser-assisted deposition Chemicals under vacuum Mask

  10. Mask Deposition DEPOSIT AFM MEASUREMENT: 1 mm 5 mm 32 nm 0 nm MATHEMATICAL DEPOSIT SIMULATION: DEPOSIT AFM MEASUREMENT: 142 nm 5 mm 0 nm MATHEMATICAL DEPOSIT SIMULATION: 5 mm

  11. The 4th dimension… ≠ fingerprints vs external conditions. A cryptographic key…

  12. Cryptography functionality 9 A first wavelength w1 is shined onto the e-tag on position (x,y). A second wavelength w2 is used to shine the e-tag on same positions (x,y) Checking of I2 values authenticates information provided by main tag. The first wavelength w1 is used to shine the e-tag on (x,y) position. 1 4 8 10 3 2 5 7 11 Alphanumeric character # is associated to light intensities value fingerprint (x, y, I1). (x ,y , #) (x ,y , I1) Light intensities values I2 associated to the tag fingerprint (x, y, I2) are recorded. I2 values are totally de-correlated from I1 The second wavelength w2 is used to shine the twin e-tag on (x,y) The message is decrypted (x, y, I1) (x, y, #) 6 TWIN TAG MAIN TAG Encrypted information (x, y, I2) is transferred

  13. Other properties available… 0 5 10 15 20 25 30 Most material properties can be modulated and patterned.

  14. ≠ LEDs Our thin film acts as a tunable color filter as a function of the wavelength. Readers External reader Integrated reader

  15. Benchmarking Digital World Quantum cryptography Software PUF Digital 3D-Tag Physical World Better and cheaper than competitors solutions

  16. TRL Roadmap • Equipments Available for small series • Physical ID Addressing industrial PoC • Digital ID Addressing Lab PoC • Mass Production Easy equipment upgrading Most experimental incertitude addressed Need to optimize the production process

  17. Conclusions All competitors functionalities PhysicalDigital Overt Firewall Covert PW generators Forensic Physical Unclonable Functions Ultra-covert Cryptography Monolithically IntegratedCMOS compatible productionNew Blockchain and AI models enabled

  18. Outlook Looking for partners: Industries / R&D Labs Co-developers Integrators Early adopters (Industrial) Venture funds Production (2 M€) Marketing + sales (3M €)
