WebMar 1, 2024 · Over the past decade, the hybrid lattice-reduction and meet-in-the middle attack (called hybrid attack) has been used to evaluate the security of many lattice-based cryptographic schemes such as NTRU, NTRU Prime, BLISS and more. However, unfortunately, none of the previous analyses of the hybrid attack is entirely satisfactory: … 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.

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. More precisely, we show that one can recover a group of equivalent private keys by solving shortest vector problem in a new dimension-reduced lattice with dimension , where is related ...

WebThe answer is NO, if NTRU is used correctly. NTRU uses structured public key a to enable efficient computation. Hence it has a trapdoor by design. So if NTRU is used in a Diffie-Hellman type key exchange, where a is generated by a (trusted) third party, then yes it may be vulnerable to this threat. However, the correct use of NTRU, in a key ... WebAug 1, 2013 · NTRU cryptosystem has been widely used in microsystems with low performance in computation.
