Performance Improvements and a Baseline Parameter Generation Algorithm for NTRUSign

Jeff Hoffstein, Nick Howgrave-Graham, Jill Pipher, Joseph H. Silverman, and William Whyte


The original presentation of the NTRUSign signature scheme gave a set of parameters that were claimed to give 80 bits of security, but did not give a general recipe for generating parameter sets to a specific level of security. In line with recent research on NTRUEncrypt, this paper presents an outline of such a recipe for NTRUSign. We also present certain technical advances upon which we intend to build in subsequent papers.

Note: Although this has been presented at a workshop, we consider it worth making the results available to a wider audience, in line with the work done on NTRUEncrypt and published on ePrint as Report 2005/045.
