#Prototype implementation in Java of NTRUReEncrypt

This repository contains a prototype implementation of NTRUReEncrypt, a Proxy Re-Encryption scheme based on NTRU, proposed by Nuñez, Agudo and Lopez, in ACM AsiaCCS 2015 [1].

This proxy re-encryption scheme extends the conventional NTRU scheme, adding functions to re-encrypt ciphertexts and to generate re-encryption keys.

This prototype implementation is built upon the NTRU implementation in tbuktu/ntru, version 1.2. Note that this prototype is a mere proof of concept so the implementation is completely monolithic. Modularization and refactoring is WIP.
