Remote Recovery of Bluetooth Chip AES‑128 Keys via RF Side‑Channel at Meter‑Scale Distance

Researchers from KTH demonstrated that a simple antenna placed about 1 meter from a Bluetooth device can capture RF emissions containing key‑related leakage, and using machine‑learning‑assisted analysis of roughly 90,000 traces they recover the full AES‑128 key, exposing a practical, non‑contact side‑channel threat and prompting hardware, firmware, and system‑level defenses.

Principles and Process of the SBC Audio Codec in Bluetooth Systems

The SBC (Subband Codec) used in Bluetooth headsets compresses PCM audio by splitting the signal into 4 or 8 sub‑bands, allocating bits according to perceptual importance, and encoding with analysis filters, scale factors, APCM and bit‑packing, then decoding reverses the process to reconstruct audio, providing lossy compression across supported sample rates and channel modes.
