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 Bernstein, Chuengsatiansup, Lange, and Vredendaal, which uses a polynomial ring that is, by design,

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.

Single-Trace Attacks on Message Encoding in Lattice-Based KEMs
IEEE Access, 2020 In this article, we propose single-trace side-channel attacks against lattice-based key encapsulation mechanisms (KEMs) that are the third-round candidates of the national institute of standards and technology (NIST) standardization project. Specifically,
