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

Lattice-based cryptography is the generic term for constructions of cryptographic primitives that involve lattices, either in the construction itself or in the security proof. Lattice-based constructions are currently important candidates for post-quantum cryptography. Unlike more widely used and known public-key schemes such as the RSA, Diffie-Hellman or elliptic-curve cryptosystems, which could, theoretically, be easily attacked by a quantum computer, some lattice-based.

It is based on problems from an area of mathematics called geometry of numbers. Suppose that one is given a square, full-rank matrix A and a value b = Ax mod p , where x is a vector with 0/1 coefficients and p is a small (e.g. 13-bit) prime Vadim Lyubashevsky, École Normale Supérieure, Paris Abstract Lattice-based cryptography is currently seen as one of the most promising alternatives to cryptography based on number theory. The major advantages of lattice-based protocols is that they are faster than ones based on number theory and they also seem to be resistant against quantum attacks
