Lattice is a linear structure,cryptosystems based on lattice have the incomparable advantage of lower energy consumption,so in the future they will also have a wide range of use for intelligent terminal.Compared with traditional public key cryptosystems: RSA,ECC,the based lattice cryptosystems can be proved secure,it has shown the important role in post-quantum cryptography era.The core of the algorithm's problems is base reduction,there are some stronger and faster algorithms under the inspiration of LLL Lattice reduction algorithm in the latest 20 years,no matter in accurate or approximate,they play an important role in cryptanalysis and cryptosystem's design.This article attempts to give an analysis and survey of all kinds of lattice reduction algorithm.
