Towards Multipronged On-Chip Memory And Data Protection From Verification To Design And Test, Senwen Kan, Jennifer Dworak
Towards Multipronged On-Chip Memory And Data Protection From Verification To Design And Test, Senwen Kan, Jennifer Dworak
Computer Science and Engineering Theses and Dissertations
Modern System on Chips (SoCs) generally include embedded memories, and these memories may be vulnerable to malicious attacks such as hardware trojan horses (HTHs), test access port exploitation, and malicious software. This dissertation contributes verification as well as design obfuscation solutions aimed at design level detection of memory HTH circuits as well as obfuscation to prevent HTH triggering for embedded memory during functional operation. For malicious attack vectors stemming from test/debug interfaces, this dissertation presents novel solutions that enhance design verification and securitization of an IJTAG based test access interface. Such solutions can enhance SoC protection by preventing memory test …
Using A Light-Based Power Source To Defeat Power Analysis Attacks, Remus Valentin Tumac
Using A Light-Based Power Source To Defeat Power Analysis Attacks, Remus Valentin Tumac
Computer Science and Engineering Theses and Dissertations
Power analysis attacks exploit the correlation between the information processed by an electronic system and the power consumption of the system. By powering an electronic system with an optical power source, we can prevent meaningful information from being leaked to the power pins and captured in power traces. The relatively constant current draw of the optical power source hides any variability in the power consumption of the target system caused by the logic gates' switching activity of the system as observed at the power pins. This thesis will provide evidence to show that using an optical power source should make …

Improving System-On-Chip Test Networks For: Bandwidth, Security, And Power, Saurabh Gupta
Computer Science and Engineering Theses and Dissertations
Modern System-on-Chips (SoCs) provide benefits such as reduction in overall system cost, and size, increased performance, and lower power consumption. Increasing complexity of these Integrated Circuits (ICs) has resulted in a higher probability of manufacturing defects. Manufacturing defects can result in the faulty operation of a system. Thus, it is essential to test an IC after it is manufactured to detect any possible faults in it. These SoCs include on-chip embedded instruments that can be used for test, debug, diagnosis, validation, monitoring, characterization, configuration, or functional purposes. IEEE 1687 Std. (IJTAG) provides a standard interface for the reconfigurable access and …

Implementation Of Switching Circuit Models As Vector Space Transformations, David Kebo Houngninou
Computer Science and Engineering Theses and Dissertations
Modeling of switching circuits is the foundation for many Electronic Design Automation (EDA) tasks and is commonly used at various phases of the design flow for tasks such as simulation, justification, and other analyses. State-of-the-art simulation tools are based on discrete event algorithms using switching algebraic models and are highly optimized and mature. Symbolic simulation may also be implemented using a discrete event approach, or other approaches based on extracted functional models. The common foundation of modern simulation tools is that of a switching or Boolean algebraic model that may be augmented with timing information. Justification using switching circuit models …
