Policy-controlled Signature From NTRU Lattice

This software is a proof-of-concept implementation of policy-controlled signature scheme over NTRU lattices, described in the paper "Policy-controlled Signature from NTRU Lattice", of Zi-Yuan Liu, Jen-Chieh Hsu, Raylin Tso, Tzong-Chen Wu

Warning

This code is not to be considered secure, efficient or fully portable. Its purpose is not to be used for actual encryption, but to provide the research community a tool to verify, analyze and reproduce the statements made in our paper.

How to use?

To modify the parameters, edit the values N0 and q0 in params.h.

To run on an Unix machine with g++:

$ make
$ ./PCS_NTRU

If GMP and NTL are not in a standard directory, you have to modify the CCFLAGS and LDFLAGS in the Makefile to indicate where they are.
