libid2 - identity-based identification library

id2 is a library for identity-based identification (ibi) for systems requiring authentication. In contrast to conventional public-key cryptosystems, the public key for id-based systems is the id of an entity itself, thereby eliminating the need for a trusted third party and storage of certificates.

Dependencies

id2 uses the following external libraries:

1. libsodium

Compile

To compile, ensure autotools such as automake, autoconf and libtool are installed.

pacman -S gcc make automake autoconf libtool
git clone https://github.com/toranova/id2 && cd id2
autoreconf --install && mkdir build && cd build && ../configure
make

To install, run following with sufficient privileges (i.e., using su or sudo)

make install

To compile and test with debugging

../configure --enable-debug --enable-tests

Supported IBI Schemes

The latest version supports 7 identity-based identification schemes. The deprecated version supports an IBI using BLS signatures
