Evaluation and Comparison of Lattice-Based Cryptosystems for a Secure Quantum Computing Era

The rapid development of quantum computing devices promises powerful machines with the potential to confront a variety problems that conventional computers cannot. Therefore, generate new threats at unprecedented speed and scale specifically pose an enormous threat encryption. Lattice-based cryptography is regarded as rival computer attack future post-quantum cryptography. So, cryptographic protocols based on lattices have benefits, such security, efficiency, lower energy consumption, speed. In this work, we study most well-known lattice-based cryptosystems while systematic evaluation comparison also presented.
