【摘要】 NTRUSign是一种基于NTRU算法的数字签名方案,该方案的安全性取决于从一个非常大的维数格中寻找最接近向量问题,NTRU数字签名方案具有密钥产生容易、速度快、占用资源少等特点.文中构造了一个新型的基于NTRUSign的持票代理签名方案,并对该方案的安全性方面作了分析.更多还原

【Abstract】 NTRUSign is a signature scheme based on NTRU.The security of the scheme is based on the hard mathematical problem of finding closest vector problem in lattices of very high dimension.Features of scheme are easy key creation,high speed and save computer resources.We constructed the new proxy signature based on the NTRUSign signature,and analyzed the essential security characters.更多还原
