“…Quantum mechanics solves the problem of key distribution-the main challenge in cryptographic schemes-with the aid of quantum superposition, quantum entanglement, and the Uncertainty Principle of Heisenberg. Heisenberg's Principle argues that two quantum states cannot be measured simultaneously [3] . This principle has as a consequence the detection of someone who tries to eavesdrop on the communication between two parties.…”

“…Regardless of superposition, quantum computers' power and capability are based on quantum physics and specifically on the phenomenon of quantum entanglement and the no-cloning system. The odd phenomenon of quantum entanglement states that there are particles that are generated, interact, and are connected, regardless of the distance or the obstacles that separate them [3]. This fundamental law of quantum physics allows us to know or to measure the state of one particle if we know or measure the other particles.…”

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

The swift advancement of quantum computing devices holds the potential to create robust machines that can tackle an extensive array of issues beyond the scope of conventional computers. Consequently, quantum computing machines create new risks at a velocity and scale never seen before, especially with regard to encryption. Lattice-based cryptography is regarded as post-quantum cryptography’s future and a competitor to a quantum computer attack. Thus, there are several advantages to lattice-based cryptographic protocols, including security, effectiveness, reduced energy usage and speed. In this work, we study the learning with errors (LWE) problem and the cryptosystems that are based on the LWE problem and, in addition, we present a new efficient variant of LWE cryptographic scheme.
