1. OpenSSL
2. Java 11 (JAVA_HOME and update-alternatives --config java both must be set up)
3. Maven
4. Node.js
5. RocksDB required libraries (refer INSTALL.md)
6. grpc (Disaggregated setups only)
7. HDFS (Disaggregated setups only)

1. The code for SHIELD is integrated into RocksDB.

2. Before building RocksDB, we need to build iotauth. We have forked iotauth from its official repository and made modifications to the codebase to work best with our deployment:

   pushd ./iotauth/examples/
   ./cleanAll.sh
   ./generateAll.sh -g ./configs/rocksdb.graph
   cd ../auth/auth-server
   mvn clean install
   java -jar target/auth-server-jar-with-dependencies.jar -p ../properties/exampleAuth101.properties
   popd

3. Change the configurations

   3.1 Search for "/path/to/db/" and replace with location to save the data encryption keys.

   3.2 Go to ./examples/c_client.config and update the paths for the public and private keys (they are located in iotauth/entity/auth_certs (and) iotauth/entity/credentials/certs/net1)

   3.3 Go to options.cc file (./options/options.cc), search for "/path/to/c_client.config" and update the path to point to the c_clients/config above.

4. Build using CMake:

   mkdir build
   cd build
   cmake -DROCKSDB_BUILD_SHARED=OFF -DWITH_TESTS=OFF -DWITH_HDFS=OFF -DWITH_EXAMPLES=OFF -DWITH_SSTLIB=ON -DWITH_CSA=OFF -DCMAKE_BUILD_TYPE=Release ..
   make -j64

1. The code for EncFS is located at: RocksDB EncFS plugin. Please follow the steps at the link to build EncFS.

2. The following will build both SHIELD and EncFS if you have completed the above SHIELD setup. Build using CMake:

   mkdir build
   cd build
   cmake -DROCKSDB_BUILD_SHARED=OFF -DWITH_TESTS=OFF -DWITH_HDFS=OFF -DWITH_EXAMPLES=OFF -DWITH_SSTLIB=ON -DWITH_CSA=OFF -DCMAKE_BUILD_TYPE=Release -DROCKSDB_PLUGINS=encfs ..
   make -j64

#Unencrypted RocksDB
./db_bench --benchmarks=fillrandom --compression_type=none

#SHIELD
./db_bench --benchmarks=fillrandom --compression_type=encrypt --wal_compression=encrypt

#EncFS
./db_bench --benchmarks=fillrandom --fs_uri="provider={id=AES;hex_instance_key=0123456789ABCDEF0123456789ABCDEF0123456789ABCDEF0123456789ABCDEF;method=AES256CTR};id=EncryptedFileSystem" --compression_type=none

Please make sure you have a second server setup and have HDFS deployed on that server. Make sure you install the RocksDB HDFS plugin.

1. Build using CMake:

   mkdir build
   cd build
   cmake -DROCKSDB_BUILD_SHARED=OFF -DWITH_TESTS=OFF -DWITH_HDFS=ON -DWITH_EXAMPLES=OFF -DWITH_SSTLIB=ON -DWITH_CSA=OFF -DCMAKE_BUILD_TYPE=Release -DROCKSDB_PLUGINS=hdfs ..
   make -j64

#Unencrypted RocksDB
./db_bench --benchmarks=fillrandom --compression_type=none --env_uri="path/to/hdfs"

#SHIELD
./db_bench --benchmarks=fillrandom --compression_type=encrypt --wal_compression=encrypt --env_uri="path/to/hdfs"

Please follow the the following commands on both servers you have.

1. Update the hdfs (hdfs_address) and the offloaded compaction path (csa_address) in the options.h file (options/options.h)

2. Search for the phrase: 'Please uncomment these lines when on the offloaded compaction server' and uncomment the 2 lines that follow that.

3. Build using CMake:

   mkdir build
   cd build
   cmake -DROCKSDB_BUILD_SHARED=OFF -DWITH_TESTS=OFF -DWITH_HDFS=ON -DWITH_EXAMPLES=OFF -DWITH_SSTLIB=ON -DWITH_CSA=ON -DCMAKE_BUILD_TYPE=Release ..
   make -j64

On Server 2 you need to update your c_client.config file to have the correct IP address of the server where you have deployed iotauth.

On server 2, run the command ./csa_server

On server 1, run the following, commands:

#Unencrypted RocksDB
./db_bench --benchmarks=fillrandom --compression_type=none --allow_remote_compaction

#SHIELD
./db_bench --benchmarks=fillrandom --compression_type=encrypt --wal_compression=encrypt --allow_remote_compaction
