Benchmarking Post-Quantum Cryptography on Resource-Constrained IoT Devices: ML-KEM and ML-DSA on ARM Cortex-M0+

The migration to post-quantum cryptography is urgent for Internet of Things devices with 10-20 year lifespans, yet no systematic benchmarks exist for the finalised NIST standards on the most constrained 32-bit processor class. This paper presents the first isolated algorithm-level benchmarks of...

CVE-2026-23519

RustCrypto CMOV provides conditional move CPU intrinsics which are guaranteed on major platforms to execute in constant-time and not be rewritten as branches by the compiler. Prior to 0.4.4, the thumbv6m-none-eabi Cortex M0, M0+ and M1 compiler emits non-constant time assembly when using cmovnz...

GHSA-2GQC-6J2Q-83QP RustCrypto Utilities cmov: `thumbv6m-none-eabi` compiler emits non-constant time assembly when using `cmovnz`

Summary thumbv6m-none-eabi Cortex M0, M0+ and M1 compiler emits non-constant time assembly when using cmovnz portable version. I did not found any other target with the same behaviour but I did not go through all targets supported by Rust. Details It seems that, during mask computation, an LLVM...

Micro:bit — A Pocket-sized Programmable Computer

The BBC has unveiled the final design of the Micro:bit — a pocket-sized computer board designed to lure U.K. school children to embedded electronics. The Micro:bit is essentially a codeable computer that lets kids get creative with technology. It measures 5cm by 4cm and will be available in...
