An FPGA based 3rd-party IP isolation mechanism

Reconfigurable architectures like Field Programmable Gate Arrays (FPGAs) are one of the most adopted solutions for computational intensive applications as they are an affordable technology compared with Application Specific Integrated Circuit. 

In addition, thanks to a growing IP Core market, one can buy third-party components to build his own system in order to meet critical contraints, like time-to-market for business applications or simply to fill the absence of expertise in a team.

A Secure and Reliable Stack Protocol for Embedded Sensor Nodes

A Design for SRAM PUF-based Secret Extractor for Resource-Constrained Devices

Trustworthiness for embedded nodes is a critical point when involved devices are resources-constrained and remotely installed. In particular, the software execution environment is jeopardized by physical attacks aimed to extract secrets:

  • Key generation and storage have to be guaranteed in a trusted manner;

  • Source of keys has to be unpredictable and random.

Physically Unclonable Functions are physical entities that maps a set of challenges to a set of response forming a set of challenge-response pairs (CPRs). A PUF exploits random imperfections introduced indirectly into the device during its manufacturing process. Its feature can be exploited to generate response that are:

  • Unique for each device where the PUF is implemented,
  • Unclonable,
  • Unpredictable,
  • Tamper-evident.

For this reasons, PUFs represent a breakthrough for silicon devices as they can be exploited as secure primitive.  Silicon PUF term indicates PUF characterized by a behavior physically imprinted into integrated circuits (ICs) in which PUFs are embedded. 

In this work, using a specific Silicon PUF available into most 

In this paper we illustrate a

pragmatic key extraction and management methodology using a specific Silicon PUF available on modern microcontroller architectures, with a real application on the STM32F7 microcontroller family, in which extracted keys are involved for remote update of ciphered software images.
