Multi-Parameter Support with NTTs for NTRU and NTRU Prime on Cortex-M4
Transactions on Cryptographic Hardware and Embedded Systems, 2022 We propose NTT implementations with each supporting at least one parameter of NTRU and one parameter of NTRU Prime. Our implementations are based on size-1440, size-1536, and size-1728 convolutions without algebraic assumptions on the target polynomial ...

Polynomial Multiplication in NTRU Prime
Transactions on Cryptographic Hardware and Embedded Systems, 2020 This paper proposes two different methods to perform NTT-based polynomial multiplication in polynomial rings that do not naturally support such a multiplication. We demonstrate these methods on the NTRU Prime key-encapsulation mechanism (KEM) proposed by

Streamlined NTRU Prime on FPGA
Journal of Cryptographic Engineering, 2022 AbstractWe present a novel full hardware implementation of Streamlined NTRU Prime, with two variants: a high-speed, high-area implementation and a slower, low-area implementation. We introduce several new techniques that improve performance, including a batch inversion for key generation, a high-speed schoolbook polynomial multiplier, an NTT polynomial

A Lightweight Implementation of NTRU Prime for the Post-quantum Internet of Things [PDF]
Lecture Notes in Computer Science, 2020 The dawning era of quantum computing has initiated various initiatives for the standardization of post-quantum cryptosystems with the goal of (eventually) replacing RSA and ECC. NTRU Prime is a variant of the classical NTRU cryptosystem that comes with a couple of tweaks to minimize the attack surface; most notably, it avoids rings with “worrisome ...

Gadget-based Masking of Streamlined NTRU Prime Decapsulation in Hardware
Transactions on Cryptographic Hardware and Embedded Systems, 2023 Streamlined NTRU Prime is a lattice-based Key Encapsulation Mechanism (KEM) that is, together with X25519, the default algorithm in OpenSSH 9. Based on lattice assumptions, it is assumed to be secure also against attackers with access to< large-scale ...

NTRU Prime: Reducing Attack Surface at Low Cost [PDF]
Lecture Notes in Computer Science, 2017 Several ideal-lattice-based cryptosystems have been broken by recent attacks that exploit special structures of the rings used in those cryptosystems. The same structures are also used in the leading proposals for post-quantum lattice-based cryptography, including the classic NTRU cryptosystem and typical Ring-LWE-based cryptosystems.

NTRU Type Fully Homomorphic Encryption Scheme over Prime Power Cyclotomic Rings [PDF]
Jisuanji kexue, 2022 Full homomorphic encryption (FHE) supports arbitrary computation on the ciphertext without the requirement of decryption,which provides protection for privacy security in cloud computing.However,the current FHE scheme constructed using the approximate ...

Provably Secure NTRU Instances over Prime Cyclotomic Rings [PDF]
Lecture Notes in Computer Science, 2017 Due to its remarkable performance and potential resistance to quantum attacks, \(\mathsf {NTRUEncrypt}\) has drawn much attention recently; it also has been standardized by IEEE. However, classical \(\mathsf {NTRUEncrypt}\) lacks a strong security guarantee and its security still relies on heuristic arguments.

Modified multi-key fully homomorphic encryption based on NTRU cryptosystem without key-switching
Tsinghua Science and Technology, 2020 The Multi-Key Fully Homomorphic Encryption (MKFHE) based on the NTRU cryptosystem is an important alternative to the post-quantum cryptography due to its simple scheme form, high efficiency, and fewer ciphertexts and keys.
