• Note: Many of instructions were compiled from below two references

• References: Link1 (English) and Link2 (Simplified Chinese)

Prerequisites (gmp, pbc, charm)

1. Before installing, you will need (if you have already installed one of them before, just skip it)

   • sudo apt-get install m4
   • sudo apt-get install -y flex
   • sudo apt-get install bison
   • sudo apt-get install -y openssl
   • sudo apt-get install -y libssl-dev

2. First, we started from gmp (gmp-6.2.1.tar.zst for example)

   • Enter super user mode (optional)

     sudo su    # or you add 'sudo' in front of every command below

   • Expand .tar.zst

     apt get install zstd    # skip if you have already installed before
     tar -I zstd -xvf gmp-6.2.1.tar.zst

   • Configure and install and check

     cd gmp-6.2.1
     ./configure
     make
     make install
     make check

   • Some dependencies should be installed finally

     apt-get install -y libgmp10 libgmp-dev

   • gmp installation complete

3. Second, we then downloaded PBC library source code (pbc-0.5.14.tar.gz for example)

   • Expand .tar

     tar -xvf pbc-0.5.14.tar.gz

   • Configure and install and check

     cd pbc-0.5.14
     ./configure
     make
     make install
     make check    # optional

   • PBC installation complete

4. Some dependencies required before getting into Charm

   • Add python PPA sources and download python 3.7 and dev

     sudo add-apt-repository ppa:deadsnakes/ppa
     sudo apt update
     sudo apt install python3.7 python3.7-dev

   • Set-up a python 3.7 environment (py37 for example, you can rename py37 as you want)

     sudo apt install virtualenv
     virtualenv -p /usr/bin/python3.7 py37
     source py37/bin/activate

   • Now your PS will look like this

     (py37) user@Ubuntu-20.04:~ $

   • Step 5 should be operated under this python environment (py37)

5. Last, access charm github project v0.50 (Version 0.50 is required if your openssl version is 1.1 or above)
   Some improvements detailed in official documentation

   • v0.50 is not released currently, so we just git clone it from this repository

     git clone https://github.com/JHUISI/charm.git

   • Install all the other dependencies and configure and install and test

     cd charm
     pip install -r requirements.txt
     ./configure.sh
     cd ./deps/pbc && make && sudo ldconfig && cd -    # this command seems downloading pbc-0.5.14.tar.gz again, maybe we can skip it, but I'm not sure with that
     make
     make install && sudo ldconfig    # is lowercase letter 'L', neither number 1 nor uppercase letter 'i'
     make test    # test your charm installation

   • After tests, it will show message look like

     ===================================== 185 passed, 3 skipped, 6 warnings in 18.36s ======================================

   • Congratulation :)
   • Charm installation complete

Attribute-Based Encryption python3 (ABE)

• See official documentation
• NOTE: we won't execute following command

  pip install -r requirements.txt    # this will install charm-crypto in old version 0.43

• First, we git clone from this repository

  git clone https://github.com/sagrawal87/ABE.git

• Compile and install

  make && pip install .

• Test ABE using samples/main.py

  python samples/main.py

• You can easily modify samples/main.py to try any scheme you wish.

• ABE installation complete

Congratulation! Welcome to the world of cryptography
