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.

NTTRU: Truly Fast NTRU Using NTT
Transactions on Cryptographic Hardware and Embedded Systems, 2019 We present NTTRU – an IND-CCA2 secure NTRU-based key encapsulation scheme that uses the number theoretic transform (NTT) over the cyclotomic ring Z7681[X]/(X768−X384+1) and produces public keys and ciphertexts of approximately 1.25 KB at the 128-bit ...

Secure data sharing technology of medical privacy data in the Web 3.0
IET Blockchain, Volume 4, Issue 4, Page 335-343, December 2024.The article proposes and implements a secure sharing model for medical privacy data based on key Web3 technologies. It constructs keyword indexes for private data, stores the source data in the Inter Planetary File System, and uses query keywords to generate trapdoors, thereby enabling the retrieval of encrypted data.

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 ...
