This paper presents a novel run-time detection mechanism, called NIGHTs-WATCH, for access-driven cache-based Side-Channel Attacks (SCAs). It comprises of multiple machine learning models, which use real-time data from hardware performance counters for ...

Caches are one of the key features of modern processors as they help to improve memory access timing through caching recently used data. However, due to the timing differences between cache hits and misses, numerous timing side-channels have been ...

This paper presents work towards realizing architectural support for Bluetooth Trusted I/O on SGX-enabled platforms, with the goal of providing I/O data protection that does not rely on system software security. Indeed, we are primarily concerned with ...

Timing channels can be exploited to leak information between two virtual machines running on a shared server. Indeed, cache timing channels are important components in the Spectre attack. A shared memory controller can also be leveraged to establish a ...

Side-channel attacks, such as Spectre and Meltdown, that leverage speculative execution pose a serious threat to computing systems. Worse yet, such attacks can be perpetrated by compromised operating system (OS) kernels to bypass defenses that protect ...

Security is evolving fast as the prime design concern for modern System-on-Chip (SoC), especially for lightweight design choices. In this manuscript, we study the design of memory protection unit (MPU) that will be integrated in RISC-V trusted SoC, with ...

RowHammer attacks pose a security threat to DRAM chips by causing bit-flips in sensitive memory regions. We propose a technique that combines a sliding window protocol and a dynamic integrity tree to rapidly detect multiple bit-flips caused by RowHammer ...

The recent Meltdown and Spectre attacks took the community by surprise. Rather than exploiting an incorrect implementation of the ISA, these attacks leverage the undocumented implementation-specific speculation behavior of high-performance ...

Hardware-assisted trusted execution environments are secure isolation technologies that have been engineered to serve as efficient defense mechanisms to provide a security boundary at the system level. Hardware vendors have introduced a variety of ...

Emerging Non-Volatile Memories (NVMs) suffer from high and asymmetric read/write current and long write latency which can result in supply noise such as supply voltage droop and ground bounce. The magnitude of supply noise depends on the old data and ...
