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.
