Project Description

This project aims to create a platform that enables users to perform private benchmarking of machine learning models. The platform facilitates the evaluation of models based on different trust levels between the model owners and the dataset owners.

This repository provides the accompnaying code for paper https://arxiv.org/abs/2403.00393

Installation

for complete build and EzPC LLM support

modify the setup.sh file to according to your system configuration for Nvidia Drivers and CUDA version (default is 11.8 and GPU architecture is 90 Hopper )
```
    (In setup.sh)
    line 42: export CUDA_VERSION=11.8
    line 43: export GPU_ARCH=90
```
run the setup.sh file
```
./setup.sh
Enter the Server IP address: 
```
- The setup.sh file will install the required dependencies and setup the environment for the platform to run. The .env file contains the django secret key which can be changed as per the user's requirement.For any key related storage, the user should only use the .env file.

only the platform

NOTE: Need to set the environment variable ENCRYPTION_KEY for the TTP/TEE server to run (32 bytes/256 bits) key and .env file manually for the platform to run and the IP address for the platform to run on.

pip install -r requirements.txt
cd eval_website/eval_website
python manage.py makemigrations
python manage.py migrate

Usage

To use the project after installation visit.

Sample User Credentials
- Model Owner
  - username: ModelOwner
  - password: helloFriend
- Dataset Owner
  - username: DatasetOwner
  - password: helloFriend
certain ports are pre-assigned as follows:
- 8000: for the main website
- 8001: for the EzPC LLM secure communication with Trusted third party server
- 7000: for the Trusted execution environment to communicate with the website
- 7001: for the Trusted third party server to receive model files
- 7002: for the Trusted third party server to receive dataset files
- 9000: for communication of Dataset owner with the website for receiving key files for EzPC
- 9001: for communication of Model owner with the website for receiving key files for EzPC
Trusted Third Party(TTP) Server
- The TTP server is a separate server that is used to perform the secure computation of the model. The TTP server is required to be running for the secure computation to be performed. The TTP server can be started by running the following command.
```
cd utils/TTP_TEE_files
python ttp_server.py
```
- Assumptions:
  - The TTP server related details are set in the platform Backend database.
  - The TTP server require to receive model and dataset files for evaluation from the respective parties on port 7001 and 7002 respectively.
  - The TTP server will perform the secure computation and return the results to the platform.
  - The TTP server also requires server.crt and server.key files to be present in the same directory as the ttp_server.py file. These files are used for secure communication between the TTP server and the platform using the CA generated by the Platform after first run and need to be generated using the following command.
```
openssl req -newkey rsa:2048 -nodes -keyout "./server.key" -out server.csr -subj /CN=127.0.0.1

openssl x509 -req -in server.csr -CA path/ca.crt(generated by eval_website root) -CAkey /path/ca.key(generated by eval_website root) -CAcreateserial -out ./server.crt -days xxx
```
- Environment Variable ENCRYPTION_KEY is required to be set for the TTP/TEE server to run (32 bytes/256 bits) key.
```
export ENCRYPTION_KEY="32 bytes key"
#generate a 32 bytes key using the following command
python -c 'import os, binascii; print(binascii.hexlify(os.urandom(32)).decode("utf-8"))'
```
Trusted Execution Environment(TEE)
- The Trusted Execution Environment is a separate server that is used to perform the secure computation of the model (based on TTP scripts). The Trusted Execution Environment is required to be running for the secure computation to be performed. Detailed instructions for setting up the Trusted Execution Environment can be found in the TTP/TEE.
EzPC LLM
- currently EzPC supports the following models
  - bert-tiny
  - bert-base
  - bert-large
  - gpt2
  - gpt-neo
  - llama7b
  - llama13b
- for more information on how to use EzPC LLM refer to the EzPC LLM.
