Previously, we were examining the instruction set. Now, it is time to conduct some microarchitectural attacks! Investigating Microarchitectural Attacks This page gives an overview of some of the microarchitectural attacks we have attempted on the Loongson dev board and our corresponding findings. Spectre Our first successful proof of concept (PoC) was for Spectre-v1. This led… » Read More

Previously, we discussed the dev board and Linux setup. Now, time to fuzz the instruction set. Loongshaker Overview Our first goal was to search for hidden or buggy instructions in the new LoongArch architecture. LoongArch is a RISC architecture with fixed-width (32-bit) instructions. As such, we decided to port armshaker to LoongArch. This program uses… » Read More

The following is a multi-part series on our evaluation of the Chinese LoongArch Architecture. This series summarizes work conducted by one of our interns, Neven J., over the course of the summer. The Chinese LoongArch architecture, developed by Loongson, is a homegrown instruction set architecture (ISA) intended to reduce reliance on foreign technologies like x86… » Read More
