Multi-Parameter Support with NTTs for NTRU and NTRU Prime on Cortex-M4
Transactions on Cryptographic Hardware and Embedded Systems, 2022 We propose NTT implementations with each supporting at least one parameter of NTRU and one parameter of NTRU Prime. Our implementations are based on size-1440, size-1536, and size-1728 convolutions without algebraic assumptions on the target polynomial ...

NTT Multiplication for NTT-unfriendly Rings
Transactions on Cryptographic Hardware and Embedded Systems, 2021 In this paper, we show how multiplication for polynomial rings used in the NIST PQC finalists Saber and NTRU can be efficiently implemented using the Number-theoretic transform (NTT).

Curve25519 for the Cortex-M4 and Beyond [PDF]
, 2019 We present techniques for the implementation of a key exchange protocol and digital signature scheme based on the Curve25519 elliptic curve and its Edwards form, respectively, in resource-constrained ARM devices. A possible application of this work consists of TLS deployments in the ARM Cortex-M family of processors and beyond.

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 ...

Optimized Implementation of PIPO Block Cipher on 32-Bit ARM and RISC-V Processors
IEEE Access, 2022 A lightweight block cipher PIPO-64/128 was presented in ICISC’2020. PIPO of the 8-bit unit using an unbalanced-bridge S-box showed better performance than other lightweight block cipher algorithms on an 8-bit AVR environment.

Polynomial multiplication on embedded vector architectures
Transactions on Cryptographic Hardware and Embedded Systems, 2021 High-degree, low-precision polynomial arithmetic is a fundamental computational primitive underlying structured lattice based cryptography. Its algorithmic properties and suitability for implementation on different compute platforms is an active area of ...

TULP4, a novel E3 ligase gene, participates in neuronal migration as a candidate in schizophrenia
CNS Neuroscience &Therapeutics, EarlyView., 2023 Mutations identified from four SCZ pedigrees resulted in decreased TULP4 expression. Tulp4 knockdown caused delayed neuron migration in embryonic mice, and impaired cognition and prepulse inhibition in adult mice. These phenotypes may be related to TULP4 through its involvement in the formation of a novel E3 ubiquitin ligases.

A Sub-mW Cortex-M4 Microcontroller Design for IoT Software-Defined Radios
IEEE Open Journal of Circuits and Systems, 2023 We present an Internet-of-Things (IoT) software-defined radio platform based on an ultra low-power microcontroller. Whereas conventional wireless IoT radios often implement a single protocol, we demonstrate that general-purpose microcontrollers running ...

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
