Side-channel attacks have become a severe threat to the confidentiality of computer
applications and systems. One popular type of such attacks is the microarchitectural attack …

The advent of the Android system has brought smartphone technology to the doorsteps of
the masses. The latest technologies have made it affordable for every section of the society …

Power side-channel attacks exploit data-dependent variations in a CPU's power
consumption to leak secrets. In this paper, we show that on modern Intel (and AMD) x86 …

In early 2018, Meltdown first showed how to read arbitrary kernel memory from user space
by exploiting side-effects from transient instructions. While this attack has been mitigated …

Power side-channel attacks exploit variations in power consumption to extract secrets from a
device, eg, cryptographic keys. Prior attacks typically required physical access to the target …

The security of computer systems fundamentally relies on memory isolation, eg, kernel
address ranges are marked as non-accessible and are protected from user access. In this …

Meltdown and Spectre enable arbitrary data leakage from memory via various side
channels. Short-term software mitigations for Meltdown are only a temporary solution with a …

To stop side channel attacks on CPU caches that have allowed attackers to leak secret
information and break basic security mechanisms, the security community has developed a …

Intel has introduced a hardware-based trusted execution environment, Intel Software Guard
Extensions (SGX), that provides a secure, isolated execution environment, or enclave, for a …
