HELR is a software project for performing a logistic regression training on encrypted data (Secure Logistic Regression based on Homomorphic Encryption: Design and Evaluation (

Step 1: brew install GMP

Step 2: brew install NTL

Step 4: cd HELR

Step 5: make new
make clean
rm *.o libHELR.a  || echo nothing to clean
