Improving lattice-based cryptographic constructions for a secure and privacy-friendly digital world

Lattice-based cryptographic constructions have long been used in post-quantum public-key cryptography. Lattice-based cryptography is also used to realize homomorphic encryption and functional encryption schemes. These schemes can facilitate provably secure privacy-preserving applications. However, as lattice-based cryptography fairly new, these applications need lots of improvement. In this project, we are planning to improve such lattice-based constructions especially the one participated in NIST's program, from both theoretical and practical perspectives. We will try to remove various bottlenecks and theoretical constraints while preserving the security of these schemes and also demonstrate the efficacy of our designs by implementations across different platforms.
