Abstract:
Cyberattacks that target hardware are becoming increasingly prevalent. These include probing attacks that aim at physically extracting sensitive information including cryptographic keys from non-volatile memory. Internet of Things devices that communicate with the Cloud are susceptible to such attacks. Therefore, the integrity of data and ability to authenticate devices are threatened. Physical Unclonable Functions (PUFs) offer a countermeasure to such attacks. A market analysis of products containing PUFs was carried out. An extract of the market analysis and the inferences that were drawn from it is provided. The analysis showed that although many different types of PUFs have been integrated into a variety of devices, most of them are still used in very rudimentary ways.
