So some cloud service providers like Amazon use custom hardware to improve different characteristics of their servers. This also means they can control the security better, because there is nothing hidden inside their silicon… Continue reading The main things a cloud data center could inject into its hardware
I’m learning about computer architecture recently, and I heard that branch prediction is really tricky but may improve the efficiency of cpu a lot, then I came across this term. My question is that is it possible to completel… Continue reading Is it possible to completely prevent Speculative Execution Side-Channel attacks?
We reported earlier about Xilinx offering free-to-use ARM Cortex M1 and M3 cores. [Adam Taylor] posted his experiences getting things working and there’s also a video done by [Geek Til It Hertz] based on the material that you can see in the second video, below.
The post covers using the Arty A35T or Arty S50 FPGA boards (based on Artix FPGAs) and the Xilinx Vivado software. Although Vivado will allow you to do conventional FPGA development, it also can work to compose function blocks to produce CPUs and that’s really what’s going on here.
The final design has an M3 …read more

Recently there has been the recommendation to disable hyperthreading. I was wondering if there is an increased risk of an attack or information disclosure when multiple virtual machines use the same CPU core or when a core is… Continue reading Security implications of running multiple virtual machines on shared CPU cores
An exploit was released for a flaw existing in a process in CPUs called Simultaneous Multithreading (SMT). Continue reading PortSmash Side-Channel Attack Siphons Data From Intel, Other CPUs
Researchers have developed an exploit that uses a feature in Intel chips to steal secret cryptographic keys. Continue reading PortSmash attack steals secrets from Intel chips on the side
Can I send instructions embedded in an image to a target, if I know his CPU architecture?
New Intel Coffee Lake CPUs offer hardware-based protections against some -but not all- Spectre and Meltdown variants. Continue reading New Ninth-Gen Intel CPUs Shield Against Some Spectre, Meltdown Variants
