摘要
格密码因其可以抵御量子计算攻击的特性和高效的加解密运算性能而被广泛研究和讨论。它基于数学中的格理论,通过将数据映射到多维空间中的格点上,利用格的特殊结构实现加密、解密及数字签名等功能。与传统密码学相比,格密码在抵抗量子计算攻击方面具有显著优势,被视为后量子密码学的重要研究方向。格密码的研究涵盖了格构造、困难问题假设、算法设计与优化等多个层面。格密码作为一种新兴的加密算法在信息安全领域展现出巨大潜力,同时它的设计与实现也面临着挑战。
Lattice cryptography has been widely studied and discussed because of its ability to resist quantum computing attack and its efficient encryption and decryption performance.Based on lattice theory in mathematics,lattice cryptography maps data to lattice points in multidimensional space,and uses the special structure of lattice to realize encryption,decryption and digital signature.Compared with traditional cryptography,lattice cryptography has significant advantages in resisting quantum computing attacks,and is regarded as an important research direction in post-quantum cryptography.The research of lattice cryptography covers many aspects,such as lattice construction,difficult problem hypothesis,algorithm design and optimization.As a new encryption algorithm,lattice cryptography has shown great potential in the field of information security,while the design and implementation of lattice cryptography are also facing challenges.
