ERIL: Extended Revocation Instruction List (v1.0)

Status: INSTANT REVOCATION ACTIVE 🏛️
Category: Zero-Knowledge Privacy-Enhancing Technology (PET)

🏛️ 1. The Revocation Problem

Traditional revocation (CRLs, OCSP) leaks the identity of the user being checked and creates latency windows. ERIL solves this by propagating revocation instructions as non-correlatable cryptographic signals.

🛡️ 2. The ERIL Protocol

🔹 Step 1: Anonymized Instruction Generation

• Input: Capability ID + User Secret + Current Time Bucket (T).
• Process: ERIL_Signal = Hash(UserSecret + Salt(T) + CapabilityID).
• Result: A unique signal that is valid only for the current 60-second time bucket.

🔹 Step 2: Global Fabric Propagation

• Action: The signal is emitted via the KetherNet fabric.
• Latency: <1 second propagation to all active Sovereign Nodes.

🔹 Step 3: Zero-Knowledge Verification

• Process: During the NovaZK-ID verification, the Sovereign Node checks if the presented credential matches any signal in the current ERIL bucket.
• Privacy: The node verifies the absence of the revocation signal without ever identifying the user or correlating multiple verification events.

⚖️ 3. Failure Semantics

If a credential matches an ERIL signal, the Sovereign Node MUST: 1. REFUSE ADMISSION immediately. 2. PURGE any cached authorization tokens for that capability. 3. EMIT a "Revocation Encountered" evidence record (sanitized).

🏁 4. Compliance Goal

ERIL satisfies the EU AI Act and GDPR "Right to be Forgotten" and "Instant Revocation" mandates without compromising user anonymity.
