A Physically Unclonable Function or PUF is a function used to generate secret information on-chip. Information such as a secret key / public key pair may be generated on-chip each time it is needed, while the secret key never needs to be output from the chip.
Thus the attack surface is reduced, since only the public key needs to be extracted from the chip. This enables Zero-Trust Onboarding.
The intrinsic properties of the PUF and its operation make it impervious to tampering: security may not be compromised.
Moreover, it is possible to enroll chips late in the manufacturing process (Zero-Touch Onboarding).
Thanks to these features, the PUF allows to enhance the security in many different applications based on cryptographic keys, such authentication protocols, data confidentiality and integrity, or Secure Boot.
By leveraging end points integrated security, the PUF advantages make it the perfect fit for connected devices life cycle management solutions such as Secure-IC iSSP, which maintains over time the right level of security for fleets of devices, during their full life-time, by mitigating the growing threats and vulnerabilities in the field and protecting end-user devices from cyberattacks at both the network and device levels, filtering attacks in real time and implementing a centralized protection mechanism for all connected modules.

CTO at Secure-IC
Sylvain Guilley is co-founder and CTO at Secure-IC. Sylvain is also professor at “Télécom ParisTech”, associate research at “École Normale Supérieure” (ENS), and adjunct professor at the Chinese Academy of Sciences (CAS). His research interests are trusted computing, cyber-physical security, secure prototyping in FPGA and ASIC, and formal / mathematical methods.
Since 2012, he organizes the PROOFS workshop, which brings together researchers whose objective is to increase the trust in the security of embedded systems. Sylvain is also lead editor of international standards, such as ISO/IEC 20897 (Physically Unclonable Functions) and ISO/IEC 20085 (Calibration of non-invasive testing tools).
Sylvain has co-authored 200+ research papers and filed 30+ patents. He is member of the IACR, and senior member of the IEEE and the CryptArchi club. He is alumni from “École Polytechnique” and “Télécom ParisTech”.
