ZipChannel

This repository contains artifacts for ZipChannel. It contains the source code of TaintChannel and the code used for the fingerprinting attacks. The code for the SGX attack from the paper is in these two repositories:

• User code: https://github.com/efeslab/ZipChannel_SGX_attack
• Kernel Driver: https://github.com/efeslab/ZipChannel_linux-sgx-driver

TaintChannel

The code in the directory dynamorio is originally from:
cloned from [https://github.com/DynamoRIO/dynamorio.git]
At commit b991249321d88117ddabd0bdf953e233928cefae

The source code for TaintChannel is in: dynamorio/api/samples/marina.cpp

to compile:

cd dynamorio
cmake -B Build
cd Build
make

to run, go to dynamorio/Build:

./bin64/drrun -c ./api/bin/libmarina.so -- bzip2 tmp.txt -kf

Code we tested TaintChannel on

We include the target libraries in submodules, to initialize them run:

git submodule init
git submodule update

Note: while ncompress and bzip2-1.0.6 contain executables, because zlib is a library it amso contains a small code to run it as an executable.

aes_T-table contains main code that invokes the vulnerable path in the AES library already installed on the syetem.

From the directory dynamorio, here are command lines for running different aplications with the TaintChannel: zlib:

make -j20 && time LD_PRELOAD=../../zlib/zlib/libz.so.1  ./bin64/drrun -c ./api/bin/libmarina.so -- ../../zlib/compress -fk |& less -R

bzip2, from the README, in order to compile as an .so run make -f Makefile-libbz2_so (I had to run make -f Makefile-libbz2_so clean first)

make -j20 && time LD_PRELOAD=../../bzip2-1.0.6/libbz2.so.1.0.6 ./bin64/drrun -c ./api/bin/libmarina.so -- bzip2 -fk ../../fingerprinting/files/alice29.txt |& less -R

make -j20 && time ./bin64/drrun -c ./api/bin/libmarina.so -- ../../ncompress/compress -fk ../../fingerprinting/files/alice29.txt |& less -R

Sample output

We include directories with sample output from TaintChannel. Each of these has its own README.

These directories contain the sample outputs from TaintChannel that were used for generating the figures:
fig_bzip2_best_gadget
fig_ncompress_best_gadget
fig_zlib_best_gadget

This is a simple example that is not included in the paper, but can be a good starting point fig_example.
