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 instead of the deprecated rustc_serialize.

This is a rust crate and comes with C bindings. For integration in distributed applications head over to rabe-keyserver, which wraps rabe in a standalone REST API webserver.

Building rabe

In order to compile and test: - install rust nightly - git clone library - install build-essential - and then run 'cargo build && RUST_BACKTRACE=1 cargo test -- --nocapture'

In order to run on the console use - target/debug/rabe

For example, in order to create msk and pk of an AC17 KP-ABE scheme run: bash $ ./target/debug/rabe --scheme AC17KP setup

To compile the C testfile: bash gcc test.c -lrabe -L./target/debug -o test
