Design of Linkable Ring Signature Scheme Based on the MP‐LWE Problem and Its Application in IoV
IET Information Security, Volume 2025, Issue 1, 2025.Ensuring the information security and privacy of users in the Internet of Vehicles (IoV) is crucial for gaining user trust and promoting the application of vehicular networks. This article designs an efficient linkable ring signature (LRS) scheme on the basis of the middle‐product learning with errors (MP‐LWE) problem and applies it to vehicular ...

Cryptanalysis of NTRU with two public keys [PDF]
, 2011 NTRU is a fast public key cryptosystem presented in 1996 by Hoffstein, Pipher and Silverman. It operates in the ring of truncated polynomials. In NTRU, a public key is a polynomial defined by the combination of two private polynomials.

Optimization of NTRU-type Multi-key Fully Homomorphic Encryption Scheme
工程科学与技术, 2020 The previous NTRU-type multi-key fully homomorphic encryption (MKFHE) schemes were constructed over power-of-2 cyclotomic polynomial rings, and the complicated key-switching operations were used in the schemes to complete the fully homomorphic ...

Revisiting LWR: A Novel Reduction Through Quantum Approximations
IET Information Security, Volume 2025, Issue 1, 2025.Pseudorandom functions (PRFs) are a very important tool in cryptography, and the learning with rounding (LWR) problem is one of the main issues in their construction. LWR problem, is to find s∈Zqn from ⌊As⌋p, where A∈Zqm×n and ⋅p:Zq→Zp is the rounding function.

Improved FHE Bootstrapping and Its Applications in Discretized Neural Networks
IET Information Security, Volume 2025, Issue 1, 2025.The inefficiency of bootstrapping is the primary bottleneck preventing fully homomorphic encryption (FHE) from practical applications. One of the main obstacles to improving the bootstrapping performance using hardware acceleration is the large storage overhead of the bootstrapping keys.

Sliding Window Method for NTRU [PDF]
, 2007 The NTRU cryptosystem is a ring-based public key system using hard problems over lattices. There has been an extensive research on efficient implementation of NTRU operations, including recent results such as Bailey et al.'s software implementation over a resource-constrained device and Gaubatz et al.'s hardware implementation using only 3,000 gates ...

IET Information Security, Volume 2025, Issue 1, 2025.The current multikey fully homomorphic encryption (MKFHE) needs to add exponential noise in the distributed decryption phase to ensure the simulatability of partial decryption. Such a large noise causes the ciphertext modulus of the scheme to increase exponentially compared to the single‐key fully homomorphic encryption (FHE), further reducing the ...

, 2005 NTRU算法是一个新的公钥密码算法,其安全性取决于从一个非常大的维数格中寻找最短向量的困难性.作者研究了NTRU算法的安全性,使用格约化方法对NTRU算法进行攻击.并找到了一类特殊的格,由于利用了NTRU私钥的特殊结构,该格的维(dimension)比常用的格更小.研究表明,具有某种特征的NTRU密钥特别容易被攻击,但是本文的方法可以用于攻击所有的NTRU密钥.该研究不会影响NTRU的应用,只是对NTRU格参数的选取有了更加严格的限制条件.从安全性和有效性综合考虑,NTRU公钥密码体制有着广阔的应用前景.
