Webattack and applicability to other key forms and the hybrid attack of [14]. It also contains possible implications for the NTRU parameters currently advised in the EEES #1 standard. 2. Preliminaries 2.1. The NTRU cryptosystem NTRU [12] is a ring-based public-key cryptosystem and a proposed alternative to RSA and ECC. WebIn this paper, we revisit the lattice attack on NTRU and present a new dimension reduction attack on NTRU without considering the pattern of private polynomials.

"WebApr 9, 2024 · Specifically, there appear to be similarities between the dual attack on LWE and the so-called “hybrid attack” [How07, Wun16] on NTRU. The hybrid attack also involves enumerating over parts of the secret, and then invoking some distinguisher to determine whether a resulting vector is close to a certain constant lattice.
