Design of hardware-orientated security towards trusted electronics.
While the Internet of Things (IoT) becomes one of the critical components in the
cyber-physical system of industry 4.0, its root of trust still lacks consideration. The
purpose of this thesis was to increase the root of trust in electronic devices by
enhance the reliability, testability, and security of the bottom layer of the IoT
system, which is the Very Large-Scale Integration (VLSI) device. This was
achieved by implement a new class of security primitive to secure the IJTAG
network as an access point for testing and programming. The proposed security
primitive expands the properties of a Physically Unclonable Function (PUF) to
generate two different responses from a single challenge. The development of
such feature was done using the ring counter circuit as the source of randomness
of the PUF to increase the efficiency of the proposed PUF. The efficiency of the
newly developed PUF was measured by comparing its properties with the
properties of a legacy PUF. The randomness test done for the PUF shows that it
has a limitation when implemented in sub-nm devices. However, when it was
implemented in current 28nm silicon technology, it increases the sensitivity of the
PUF as a sensor to detect malicious modification to the FPGA configuration file.
Moreover, the efficiency of the developed bimodal PUF increases by 20.4%
compared to the legacy PUF. This shows that the proposed security primitive
proves to be more dependable and trustworthy than the previously proposed
approach.Samie, Mohammad (Associate)PhD in Transport System
