WebAbstract. NTRUE ncrypt is unusual among public-key cryptosystems in that, with standard parameters, validly generated ciphertexts can fail to decrypt. This affects the provable security properties of a cryptosystem, as it limits the ability to build a simulator in the random oracle model without knowledge of the private key. Web19,26,18,3,9,28] were proposed aiming at NTRU family, and NTRUEncrypt is generally believed to be secure in practice. However, classical NTRU lacks a solid security guarantee, which may weaken our con dence in this scheme.
