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
