This paper introduces novel high-precision Branch Target Injection (BTI) attacks, leveraging
the intricate structures of the Indirect Branch Predictor (IBP) and the Branch Target Buffer …

This paper introduces novel attack primitives that enable adversaries to leak (read) and
manipulate (write) the path history register (PHR) and the prediction history tables (PHTs) of …

The effectiveness of transient execution defenses rests on obscure model-specific
operations that must be correctly implemented in microcode and applied by software. In this …

ARM's TrustZone is a hardware-based trusted execution environment (TEE), prevalent in
mobile devices, IoT edge systems, and autonomous systems. Within TrustZone, security …

Transient execution attacks constitute a major class of attacks affecting all modern out-of-
order CPUs. These attacks exploit transient execution windows (ie, the instructions that …

Modern Out-of-Order (OoO) CPUs are complex systems with many components interleaved
in non-trivial ways. Pinpointing performance bottlenecks and understanding the underlying …

With the emergence and proliferation of microarchitectural attacks targeting branch
predictors, the once-established security boundary in computer systems and architectures is …

The constant-time property is considered the security standard for cryptographic code. Code
following the constant-time discipline is free from secret-dependent branches and memory …
