Simulation Trail Authentication System (STAS) Classification: High‑Assurance Security Architecture — Conceptual Framework with Implementation Guidance (parameters withheld) Author: ZeroDriveX Status: Draft v1.0 (Delivery) --- Abstract This paper presents the Simulation Trail Authentication System (STAS), a high‑assurance authentication and authorization primitive based on consumable, state‑bound entropy produced by a controlled simulation runtime. STAS replaces long‑lived secrets, renewable tokens, and clock‑based authentication with finite, single‑use authority derived from aligned simulation trail states. Each authorization event irreversibly consumes one unit of authority; when no unconsumed trail states remain, authority ends. STAS is designed for environments where compromise is unacceptable, secrets must not persist, and autonomy—when permitted—must be strictly scoped. The system supports cloud control planes, confined Kubernetes workloads, edge/IoT devices, laptops, and mobile endpoints, while maintaining a public‑facing simulation surface that is non‑authoritative until authentication enables persistence. --- Design Principles STAS is governed by the following non‑negotiable principles: 1. Finite Authority: Authorization material is exhaustible. There is no silent renewal. 2. Single‑Use: Each valid artifact is consumed exactly once (burn‑on‑use). 3. State‑Bound: Validity depends on simulation state, run context, and session scope. 4. Contextual Time: Time is represented by session and run boundaries, not wall‑clock values. 5. Capability over Knowledge: Possession of data is insufficient without the correct context and ledger state. 6. Clean Failure: Exhaustion or misalignment results in denial without side‑channel leakage. --- System Overview STAS comprises four layers: 1. Simulation Runtime — Produces evolving particle states and trails. 2. Qualification Layer — Applies decay and alignment rules to determine survivable artifacts. 3. Persistence & Ledger — Stores only aligned, surviving trail commitments under authenticated control. 4. Consumption Interface — Validates, consumes, and irreversibly burns artifacts during authorization. A public simulation mode exists for exploration and visualization. Security relevance begins only when authentication enables persistence. --- Runtime Modes Guest Mode (Public) Persistence: Disabled Identity: GUEST Trails: Ephemeral Authority: None Guest mode is explicitly non‑authoritative. The runtime is incapable of producing or retaining security‑relevant state. Authenticated Mode Persistence: Enabled Identity: Bound to session Trails: Durable (subject to qualification) Authority: Finite and consumable Authentication does not unlock features; it enables conservation of state. --- Simulation Qualification Decay A probabilistic decay (e.g., 50/50) is applied to candidate particles. Decayed or collapsed particles are discarded and never reach persistence. Decay throttles issuance and prevents hoarding. Alignment Only particles maintaining alignment under runtime rules are eligible. Alignment represents coherence and survivability. Misaligned particles decay and are removed. Result: Only aligned, surviving trails are persisted. --- Run Isolation and Session Binding Each authenticated run generates a session hash that cryptographically binds all persisted trails to: the current simulation run the authenticated session window Trails from different runs or sessions are incompatible. Cross‑run replay, mixing, or splicing is invalid by construction. --- Trail Artifacts A trail artifact is an ordered, state‑derived unit that becomes authorization material only within STAS. Outside the system it is inert numeric data. Trail validity requires all of the following: 1. Authenticated persistence enabled at creation 2. Survival through decay 3. Alignment at extraction 4. Correct run/session binding 5. Unconsumed ledger state 6. Correct sequence --- Ledger and Burn Semantics The ledger is an authority conservation mechanism: Each valid trail is recorded once Consumption is atomic Successful use deletes the ledger entry Reuse is impossible Deletion (burn) is preferred over marking to prevent ambiguity and replay. --- Authorization Semantics STAS authorizes actions, not identities. Examples: One Kubernetes control‑plane operation One edge device command One admin action on a laptop One human approval on mobile Each action consumes exactly one trail. When trails are exhausted, authority ends. --- Time‑Scoped Usage STAS is time‑scoped without relying on clocks. Validity exists only: within the authenticated session window within the active simulation run Trails generated outside the session or consumed after logout are invalid. --- Regeneration and Forward Security A minimal control‑parameter adjustment produces a new entropy universe: Future trails diverge completely Past modeling becomes useless Existing unconsumed trails remain valid only within their original context This enables instant forward‑security resets without mass rotation events. --- Threat Model (Summary) Mitigated Credential replay Offline attacks Long‑lived secret compromise Token hoarding Clock manipulation Silent privilege persistence Assumptions Integrity of the persistence/ledger layer Secure transport for live sessions Physical compromise remains a system‑level risk --- Operational Fit STAS is intentionally narrow in audience and broad in correctness. It is suitable for: High‑assurance infrastructure Confined Kubernetes clusters Edge/IoT in hostile environments Privileged admin workflows Scoped autonomy It is not intended for consumer authentication or recovery‑heavy workflows. --- Acceptable Autonomy Autonomous systems may act only while possessing unconsumed authority. Each action burns authority. Autonomy ends when authority is exhausted. This property makes autonomy auditable, finite, and defensible. --- Conclusion STAS defines authentication as finite, consumable authority bound to irreversible state evolution. By eliminating renewable secrets and enforcing burn‑on‑use semantics, the system provides clean failure, forward security, and strict scoping suitable for the most demanding environments. --- Appendix A — Confined Variant for Local Agents (Non‑Public) Purpose This variant applies STAS principles to local, confined agents without exposing a public simulation surface. Differences from Public STAS No guest mode or public runtime Simulation runs headless and sealed Trails never exported as artifacts Consumption occurs via local capability checks Use Cases Local autonomous agents On‑device decision systems Confined remediation tools Air‑gapped or single‑host environments Model Simulation initialized with sealed parameters Authority budget pre‑allocated as internal trails Each agent action consumes one internal trail No external visibility or reuse Benefits Same finite‑authority guarantees No public exposure Minimal surface area Deterministic containment Summary The confined variant preserves the core invariant—authority is finite and exhaustible—while eliminating public interfaces. It is appropriate where local autonomy must be powerful yet strictly bounded. --- End of Document?
