Physical Unclonable Functions (PUF) are an emerging hardware security primitives proposed by various researchers in last one decade. PUFs are useful security architectures used for identification, authentication and cryptographic key generation. Many PUF topologies are proposed in the past targeting both ASIC and FPGA. It is nearly impossible to get two PUF circuits with same characteristics for the...
Cyber-physical system integrity requires both hardware and software security. Many of the cyber attacks are successful as they are designed to selectively target a specific hardware or software component in an embedded system and trigger its failure. Existing security measures also use attack vector models and isolate the malicious component as a counter-measure. Isolated security primitives do not...
The information and control system of smart building is considered as a set of subsystems including a building automation system (BAS). BAS security and availability during its life cycle are assessed using the Attack Tree Analysis (ATA) and Markov models. The ATA is applied to investigate any intrusions into the BAS by analyzing system probability of a fault/vulnerability to occur during period of...
This paper proposes Flex Core, a hybrid processor architecture where an on-chip reconfigurable fabric (FPGA) is tightly coupled with the main processing core. Flex Core provides an efficient platform that can support a broad range of run-time monitoring and bookkeeping techniques. Unlike using custom hardware, which is more efficient but often extremely difficult and expensive to incorporate into...
To the best of the authors' knowledge, this is the first brief that implements a complete automatic fingerprint-based authentication system (AFAS) application under a dynamically partial self-reconfigurable field-programmable gate array (FPGA). The main benefits of this implementation are the acceleration of the processing reached by the parallelism inherent to the hardware design, the high level...
