Web29 de out. de 2014 · 1 Answer. Sorted by: 7. NTRU, as it was originally introduced, is based on what people now call the "NTRU assumption", which really just assumes that it is difficult to break NTRU. Annoyingly circular, but that's how it is. Similar to how breaking RSA is not provably as hard as factoring (technically it is based on the "RSA assumption"), but ... Web31 de jan. de 2001 · Optimizations for NTRU.

Webstructed the rst provably secure CRPSF [16] over power-of-two cyclotomic elds based on NTRU. Then, by using GPV’s construction, they gave the rst provably secure NTRUSign. As far as we know, CRPSF constructed in [39] was the rst one which constructed in rings and used the hardness of worst-case ideal lattice problems over corresponding cyclotomic 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.
