Information flow tracking (IFT) is a fundamental computer security technique used to
understand how information moves through a computing system. Hardware IFT techniques …

A timing channel is a communication channel that can transfer information to a
receiver/decoder by modulating the timing behavior of an entity. Examples of this entity …

Security for Internet-of-Things devices is an increasingly critical aspect of computer
architecture, with implications that spread across a wide range of domains. We present the …

Micro-architecture units like caches are notorious for leaking secrets across security
domains. An attacker program can contend for on-chip state or bandwidth and can even use …

We introduce a compiler that automatically inserts software countermeasures to protect
cryptographic algorithms against power-based side-channel attacks. The compiler first …

The impending realization of scalable quantum computers will have a significant impact on
today's security infrastructure. With the advent of powerful quantum computers public key …

In the process of globalization, heterogeneous SoCs play an important role in an embedded
application, security aspects of such a system are crucial. The system is susceptible to many …

Security and reliability have become important concerns in the design of computer systems.
On one hand, microarchitectural enhancements for security (such as for dynamic integrity …

Modern applications often host or process code and data from many mutually distrusted
entities referred to as security domains. Ensuring the data privacy and security of these …

Military electronics rely on commodity processors, many of which are manufactured
overseas where the trustworthiness of the foundries is uncertain. This thesis attempts to …
