MSPEP v6 — Multi-Source Physical Entropy Pool Encryption (Defensive Publication)

MSPEP v6 (Multi-Source Physical Entropy Pool Encryption) is a cryptographic system that harnesses multiple physical sensors on a device (e.g., magnetometer, thermistors, accelerometer, microphone, photodiode, RF front-end, power rail noise, NIC timing) to create a continuous entropy pool. It selects random subsets of at least three sensors per event within bounded sampling windows, applies adaptive entropy weighting, and uses cryptographic extractors (HKDF/SHA3) with continuous reseeding to generate secure keys. The system supports various security applications including AI session security, which features per-session keys derived from client physical entropy, continuous integrity monitoring, and anomaly response mechanisms. The architecture involves client-side key generation and server-side validation of physical fingerprints without key transmission. The design and prior art are openly published as a defensive publication with no associated vulnerability or exploit information.

There is no indication of a security vulnerability or exploit associated with MSPEP v6. The publication describes a cryptographic method intended to enhance security through hardware-rooted entropy sources. No adverse impact or threat is reported.

No mitigation actions are required as this is a defensive publication of a cryptographic system, not a vulnerability or threat. Users and implementers should review the published specification and assess suitability for their security needs.
