Talk:NTRU

It would be nice to add information about patents or the lack thereof. 69.117.132.54 (talk) 00:03, 4 February 2013 (UTC) Patent info can be found here: https://github.com/NTRUOpenSourceProject/ntru-crypto/blob/master/COMMERCIAL%20LICENSE.doc?raw=true

The Open Source version mentioned on reference 1 (Buktu, Tim. "NTRU: Quantum-Resistant cryptography". NTRU Cryptosystems, Inc. Retrieved February 4, 2013.) is not authorized by Security Innovation (who acquired NTRU) and use of that version violates NTRU patents. That link should be removed and replaced by the official version https://github.com/NTRUOpenSourceProject/ntru-crypto

There have been more than 20 research papers published on NTRU. They can be found here: https://securityinnovation.com/security-lab/crypto/402.-scrutiny-ntru-encrypt.html

Re. violation of NTRU patents: that's no longer true since they made an exception for FOSS code: https://github.com/NTRUOpenSourceProject/ntru-crypto/blob/master/FOSS%20Exception.md 190.73.117.158 (talk) 19:05, 15 December 2014 (UTC)

Origin of name "NTRU"?
Does anybody know where the name "NTRU" came from? It's not the initials of the inventors. (That would maybe be "SLiP-H" - perhaps not the best name for a cryptosystem :) Jimw338 (talk) 18:55, 2 March 2019 (UTC)

The webpage had stated, without attribution, that "NTRU is an abbreviation for "Nth degree‐truncated polynomial ring units." This is a clever guess, but it is not correct, at least not as far as the inventors are aware. In the early days, corporate types and investors were told that NTRU stood for "Number Theory Research Unit," which is not unreasonable, since two of the three inventors (Hoffstein and Silverman) are number theorists. (Pipher's primary field is harmonic analysis.) However, there are also those who believe that the name was originally a riff on a popular toy store chain: NTRU = Number Theorists "R" Us.

And although Jimw338 is correct that using last name initials could have lead to an unfortunate name, there was actually some thought of calling it JJJ for the first names Jeffrey (Hoffstein), Jill (Pipher), Joseph (Silverman), which would have been amusing in view of the famous LLL lattice reduction algorithm, which is one of the tools used to analyze the security of NTRU.

Lattice attacks of Coppersmith and Shamir.
How come the devastating lattice attack of Coppersmith and Shamir not mentioned on this page?
