摘　　要：NTRU(Number Theory Research Unit)是一种新型的公钥密码体制,因其高效、快速和运算简单等特点,已得到越来越广泛的应用.其安全性建立在大维数格中的数学难题之上,为此,在研究NTRU算法和格理论的基础上,设计了一种建立在最近向量难题上的数字签名方案.NTRU is a new kind of public-key cryptosystem. It already gets more and more applications because of characteristics such as high-efficiency, fast and easy-operation. The security of the NTRU public-key cryptosystem is based on the hard lattice problem. Then one kind of digital signature scheme was designed on the basis of studying the NTRU algorithm and lattice theory. The scheme is established on the closest vector problem.
