Spectre attack code #3

Open pluviophilee opened 4 years ago

pluviophilee commented 4 years ago

Hi, I have tried spectre code on unsafe mode, but it does not work. Do you have the sample spectre attack code which is used in your experiment?

Can you leave your error message?

I run the spectre attack code in Invisispec https://github.com/mjyan0720/InvisiSpec-1.0/blob/master/attack_code/spectre_full.c with the command line build/X86_MESI_Two_Level/gem5.opt config/example/se.py --num-cpus=1 --mem-size=4GB --caches --l1d_assoc=8 --l2_assoc=16 --l1i_assoc=4 --cpu-type=DerivO3CPU --threat_model=UnsafeBaseline --needsTSO=0 --STT=0 --implicit_channel=0 0c spectre_full. The result shows that the spectre attack is not successful.

The successful result should be like this.

I didn't try this attack code before. Although I think in the first picture, part of the private text is extracted. To extract all the text, you probably need to tweak the parameters in the code, or change the processor configuration of gem5 to make it more obvious.

Could you please share your attack test code？
