In this project we implemented a TDH construction from the DDH in [DGI+19], from the project list. To demonstrate the applications of this constructions we implemented the Rate-1 OT protocol in section 5.3.
## Project Structure
```
.
|-- bOT.py
|-- __init__.py
|-- README.md
`-- tdh_ddh.py
```
* `tdh_ddh.py` - code that contains the TDH.
* `bOT.py` - code that implements the OT protocol.
## Requirements
In this project we require the `pycrypto` python library. If not already installed use:
```sh
sudo python -m pip install pycrypto
```
## How to use
`bOT.py` takes in tree arguments as input:
* `sp` - security parameter
* `k` - number of bits in the secrets
* `n` - number of secrets
To execute with `sp=16`, `k=8`, `n=16` do:
```sh
python bOT.py 16 8 16
```
