Lattice-Based Cryptography Oded Regev Tel Aviv University, Israel Abstract. We describe some of the recent progress on lattice-based cryptography, starting from the seminal work of Ajtai, and ending with some recent constructions of very efficient cryptographic schemes. 1 Introductio Lattice Based Cryptography : This approach is based on Lattice-based constructions. Ajtai[9], in 1996 introduced the rst lattice based cryptographic protocol, based on the lattice problem - Short Integer Solutions. More recently, works revolve around Regev's[1] lattice based public key encryption key based on Learning With Errors problem

For the purposes of this post, I will focus on the problem family used in what is usually referred to as lattice-based cryptography

1. Lattice-based cryptography itself is fairly well understood, exploiting lattice problems as a hardness assumption. Lattice-based cryptography is one of only a few popular designs for post-quantum cryptography. There are others, such as code-based cryptography, multivariate polynomial cryptography, and hash-based signatures
2. Currently used forms of cryptography will be broken by supercomputers, and lattices have been shown to provide efficient, secure solutions with multi-functional capabilities. Sarah's research contributes towards ensuring these lattice-based primitives are secure against algorithmic and physical attacks, and are lightweight enough to be run on modern devices such as those used in the Internet.

1. Post-quantum cryptography (sometimes referred to as quantum-proof, quantum-safe or quantum-resistant) refers to cryptographic algorithms (usually public-key algorithms) that are thought to be secure against a cryptanalytic attack by a quantum computer.As of 2021, this is not true for the most popular public-key algorithms, which can be efficiently broken by a sufficiently strong quantum computer
2. In this paper, we first present a new lattice-based PKE scheme on SIS, proving that it achieves CPA-security under DBi-ISIS assumption. Compared to some lattice-based schemes, ours has some advantages and is quite efficient as well as great simplicity. Similarly, we give a lattice-based PKE with multiple bits which is CPA secure under DBi-ISIS assumption
