Some great developments in lattice-based crypto. DJB just released a paper on NTRU Prime: 1. Competitively fast compared to the leading lattice-based cryptosystems including New Hope. 2. Safer implementation of NTRU that avoids vulnerable ring structures and runs in constant-time. 3. The only implemntation that mitigates decryption failures completely, killing information leaks to adversaries. 4. Includes some handy advice for "transitional cryptography" - mixing and matching classical signature schemes with PQ public-keys. https://ntruprime.cr.yp.to/ntruprime-20160511.pdf
