基于NTRU的全同态加密方案
A Fully Homomorphic Encryption Scheme Based on NTRU
摘要
Abstract
A fully homomorphic encrgption scheme was presented based on number theory research unit (NTRU),which is provable security about indistinguishable chosen plaintext attack (IND-CPA).Firstly,to avoid the effective lattice attacks,we modified the key generation algorithm of NTRU by Gaussian abstraction algorithm of lattices,and the distribution of the key is not changed.Then,we proposed a new homomorphic encrypfion scheme based on the improved NTRU encryption algorithm by using the Flattening technique.Its IND-CPA security was proved strictly under the standard model.关键词
