Preface to special topic on lattice-based cryptography. [PDF]
Natl Sci Rev, 2021 Classical cryptography has been around for a long time in the documented human history, but most classical ciphers were broken and even solved by hand.

Improved Plantard Arithmetic for Lattice-based Cryptography
Transactions on Cryptographic Hardware and Embedded Systems, 2022 This paper presents an improved Plantard’s modular arithmetic (Plantard arithmetic) tailored for Lattice-Based Cryptography (LBC). Based on the improved Plantard arithmetic, we present faster implementations of two LBC schemes, Kyber and NTTRU, running ...

The Ring-LWE Problem in Lattice-Based Cryptography: The Case of Twisted Embeddings. [PDF]
Entropy (Basel), 2021 Several works have characterized weak instances of the Ring-LWE problem by exploring vulnerabilities arising from the use of algebraic structures. Although these weak instances are not addressed by worst-case hardness theorems, enabling other ring ...

Higher-Order Masked Ciphertext Comparison for Lattice-Based Cryptography [PDF]
Transactions on Cryptographic Hardware and Embedded Systems, 2022 Checking the equality of two arrays is a crucial building block of the Fujisaki-Okamoto transformation, and as such it is used in several post-quantum key encapsulation mechanisms including Kyber and Saber.

Symbolic Proofs for Lattice-Based Cryptography [PDF]
Proceedings of the 2018 ACM SIGSAC Conference on Computer and Communications Security, 2018 Symbolic methods have been used extensively for proving security of cryptographic protocols in the Dolev-Yao model, and more recently for proving security of cryptographic primitives and constructions in the computational model. However, existing methods for proving security of cryptographic constructions in the computational model often require ...

Investigating Lattice-Based Cryptography [PDF]
, 2022 Cryptography is important for data confidentiality, integrity, and authentication. Public key cryptosystems allow for the encryption and decryption of data using two different keys, one that is public and one that is private.

Kavach: Lightweight masking techniques for polynomial arithmetic in lattice-based cryptography
Transactions on Cryptographic Hardware and Embedded Systems, 2023 Lattice-based cryptography has laid the foundation of various modern-day cryptosystems that cater to several applications, including post-quantum cryptography. For structured lattice-based schemes, polynomial arithmetic is a fundamental part. In several
