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 ...

Algebraic attack on NTRU using Witt vectors and Gröbner bases
Journal of Mathematical Cryptology, 2009 We present an algebraic attack on NTRU (restricted to the case where the parameter q is a power of two) using the method of the Witt vectors proposed by Silverman, Smart and Vercauteren [Springer: 278–298, 2005]; the latter considered only the first two ...

New practical algorithms for the approximate shortest lattice vector [PDF]
, 2005 We present a practical algorithm that given an LLL-reduced lattice basis of dimension n, runs in time O(n3(k=6)k=4+n4) and approximates the length of the shortest, non-zero lattice vector to within a factor (k=6)n=(2k). This result is based on reasonable

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.

Proposal for Two Enhanced NTRU [PDF]
International Journal of Advanced Computer Science and Applications, 2014 Sound is very widely used in communication. In order to ensure secure communication a cryptographic data scheme is used. Secure sound is needed in many fields such as military, business, banking and electronic commerce. There is also an increasing demand for secured sound in network communication.

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 ...
