Memory-Efficient High-Speed Implementation of Kyber on Cortex-M4

, 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 ...

Integrated Analysis of Brain Transcriptome Reveals Convergent Molecular Pathways in Autism Spectrum Disorder

Frontiers in Psychiatry, 2019
Autism spectrum disorder (ASD) is a set of complex neurodevelopmental disorders with etiology that remains elusive. Although there is a mounting body of investigation in different brain regions related to ASD, our knowledge about the common and distinct ...

Constant-Time Bitsliced Rijndael-256 on ARM Cortex-M4: On the Limitations of Fixslicing Beyond AES-128

International Islamic University Malaysia Engineering Journal
Wider-block ciphers are increasingly needed in high-volume applications, because 128-bit blocks in modes such as Galois/Counter Mode (GCM) limit each invocation to roughly 64 GiB of plaintext per key-nonce pair, forcing complex re-keying strategies ...

KyberSlash: Exploiting secret-dependent division timings in Kyber implementations

Transactions on Cryptographic Hardware and Embedded Systems
This paper presents KyberSlash1 and KyberSlash2 – two timing vulnerabilities in several implementations (including the official reference code) of the Kyber Post-Quantum Key Encapsulation Mechanism, recently standardized as ML-KEM.

Transcriptomic analysis of rat prefrontal cortex following chronic stress induced by social isolation – Relevance to psychiatric and neurodevelopmental illness, and implications for treatment

Neurobiology of Stress
Social isolation is an established risk factor for psychiatric illness, and became increasingly topical with the spread of SARS-CoV-2. We used RNA sequencing (RNA-Seq) to enable unbiased assessment of transcriptomic changes within the prefrontal cortex ...
