Keyless Computing System and Method using Deterministic Regeneration and Provable Zeroization based on Biometric-Spacetime Fusion

Traditional computing systems inherently depend on persistent storage for cryptographic keys and sensitive data, creating a permanent attack surface for theft and compromise. This paper introduces a "Keyless Computing" paradigm that eliminates the need for key storage entirely. We propose a system based on "Deterministic Regeneration" and "Provable Volatile Zeroization," where cryptographic keys are synthesized in real-time using a deterministic fusion of user biometrics and dynamic spatiotemporal context. Specifically, the system utilizes Heart Rate Variability (HRV) and Electrocardiogram (ECG) signals as dynamic liveness seeds, combined with high-precision Latitude, Longitude, Altitude, Barometric Pressure, Wi-Fi RSSI, and Nanosecond-level Time. To address physiological signal variability, fuzzy extractors and error correction codes are employed to ensure deterministic key derivation. The generated keys exist only in volatile memory during a single atomic transaction and are immediately destroyed (zeroized) upon completion. This approach shifts the security model from "defending stored secrets" to "proving operational context," ensuring resilience against physical theft and future quantum computing threats.
