Memory-Efficient High-Speed Implementation of Kyber on Cortex-M4
IACR Cryptology ePrint Archive, 2019 This paper presents an optimized software implementation of the module-lattice-based key-encapsulation mechanism Kyber for the ARM Cortex-M4 microcontroller. Kyber is one of the round-2 candidates in the NIST post-quantum project. In the center of our work are novel optimization techniques for the number-theoretic transform (NTT) inside Kyber, which ...

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.

Fast Strategies for the Implementation of SIKE Round 3 on ARM Cortex-M4
IEEE Transactions on Circuits and Systems Part 1: Regular Papers, 2021 The Supersingular Isogeny Key Encapsulation mechanism (SIKE) is the only post-quantum key encapsulation protocol based on elliptic curves and isogeny maps between them. Despite the quantum security of the protocol, SIKE requires a greater number of clock

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.

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.

Improving Single-Trace Attacks on the Number-Theoretic Transform for Cortex-M4
IEEE International Symposium on Hardware Oriented Security and Trust, 2023 The Number-Theoretic Transform (NTT) is a key feature for the efficiency of numerous lattice-based cryptographic schemes. The arithmetic structure of that operation makes it an important target for soft-analytical side-channel attacks, that are powerful ...
