Memory-based Combination PUFs for Device Authentication in Embedded Systems

Embedded systems play a crucial role in fueling the growth of the Internet-of-Things (IoT) in application domains such as healthcare, home automation, transportation, etc. However, their increasingly network-connected nature, coupled with their ability to access potentially sensitive/confidential information, has given rise to many security and privacy concerns. An additional challenge is the growing number of counterfeit components in these devices, resulting in serious reliability and financial implications. Physically Unclonable Functions (PUFs) are a promising security primitive to help ad…

Towards a Supply Chain Management System for Counterfeit Mitigation using Blockchain and PUF

The complexity of today's supply chain, organised in several tiers and including many companies located in different countries, makes it challenging to assess the history and integrity of procured physical parts, and to make organisations really accountable for their conduct. This enables malicious practices like counterfeiting and insertion of back doors, which are extremely dangerous, especially in supply chains of physical parts for industrial control systems used in critical infrastructures, where a country and human lives can be put at risk. This paper aims at mitigating these issues by p…
