# Rabe



rabe is a rust library implementing several Attribute Based Encryption (ABE) schemes using a modified version of the `bn` library of zcash (type-3 pairing / Baretto Naering curve). The modification of `bn` brings in `serde` or `borsh` instead of the deprecated `rustc_serialize`.

The standard serialization library is `serde`. If you want to use `borsh`, you need to specify it as feature.

# WARNING !

The YCT14 scheme was broken in [1] and a 'fixed' version was again broken in [2].

Demonstration how the attack can be implemented in practice in https://www.blackhat.com/eu-21/briefings/schedule/index.html#practical-attacks-against-attribute-based-encryption-25058.

# Building rabe lib



In order to compile and test:

- install rust nightly

- git clone library 

- install build-essential

- and then run `cargo build --release && RUST_BACKTRACE=1 cargo test -- --nocapture` 

- rabe is also available with borsh serialization. just add `--no-default-features --features borsh` to the build command



# Building rabe console app



See [README.md](./rabe-console/README.md)
