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 ...

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.

High-Speed Key Encapsulation from NTRU
, 2017 This paper presents software demonstrating that the 20-year-old NTRU cryptosystem is competitive with more recent lattice-based cryptosystems in terms of speed, key size, and ciphertext size. We present a slightly simplified version of textbook NTRU, select parameters for this encryption scheme that target the 128-bit post-quantum security level ...

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.

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 ...

Optimized Design and Implementation of CRYSTALS‐KYBER Based on MLWE
Security and Communication Networks, Volume 2025, Issue 1, 2025.CRYSTALS‐KYBER is a postquantum key exchange mechanism based on the MLWE problem. At present, it is a major challenge to realize CRYSTALS‐KYBER with high‐performance and low‐resource consumption on the FPGA platform. The design proposed in this paper aims at the high efficiency implementation of CRYSTALS‐KYBER based on the MLWE scheme.
