Fuzzer coverage

[bashirshabir]

This is great research for TEE fuzzing. I see that the fuzzer has not been released yet. Looking forward to checking it out.
One thing I did not get from the paper was how exactly you extracted the coverage for TEEzz.
Will you be providing some tool to extract coverage along with fuzzer itself?

Hi @bashirshabir,

Thanks for your interest in TEEzz!

On COTS devices, TEEzz is a black-box fuzzer. For the coverage evaluation shown in the paper, we measured the coverage of our black-box approach using OPTEE. OPTEE is open-source and we modified it to extract coverage information. To answer your question, yes, our modified OPTEE will be released as well.
