Boosting the hybrid attack on ntru

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 29, 2024 · NTRU is a very efficient public-key cryptosystem based on polynomial arithmetic. Its security is related to the hardness of lattice problems in a very special class of lattices. This article is ...

We revisit collision attacks on NTRU, namely Odlyzko's meet-in-the-middle attack and Howgrave-Graham's hybrid attack. We show how to simplify and improve these attacks with respect to efficiency, analysis and ease of implementation. …

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 ...
