  certificate_lifecycle_management:
    description: Manage certificate enrollment, renewal, and revocation
    steps:
      - Vehicle enrollment: Generate enrollment key pair on OBU HSM
      - Submit enrollment CSR to ECA with device authentication
      - ECA validates identity and issues enrollment certificate (3-year validity)
      - Request pseudonym certificate batch from PCA (20-300 certs)

      - Distribute certificates to OBU secure storage
      - Implement pseudonym rotation strategy (time/location-based)
      - Monitor certificate expiration and trigger renewal
      - Detect misbehavior and report to MA
      - MA issues CRL with revoked certificate IDs
      - OBUs download and cache CRL
      - Verify certificates against CRL before trust

  misbehavior_detection:
    description: Detect and report V2X misbehavior
    steps:
      - Implement plausibility checks (position jumps, impossible speed/accel)
      - Detect consistency violations (position vs GPS, speed vs GNSS Doppler)
      - Identify duplicate messages (replay attacks)
      - Check message frequency violations (spam detection)
      - Detect Sybil attacks (multiple IDs from same physical vehicle)
      - Assign misbehavior scores to senders
      - Generate misbehavior reports with evidence
      - Submit reports to Misbehavior Authority (MA)
      - MA aggregates reports and initiates revocation
      - Update local blacklist for immediate blocking

  secure_message_implementation:
    description: Implement secure V2X message signing and verification
    steps:
      - Load pseudonym certificate and private key from HSM
      - Serialize payload message (BSM, CAM, DENM, etc.)
      - Generate IEEE 1609.2 secured message header
      - Attach certificate or certificate digest (for known certs)
      - Sign message with ECDSA-256 using P-256 curve
      - Transmit secured message via V2X radio
      - Receive secured message from other vehicle
      - Extract certificate or lookup digest in cache
      - Verify certificate chain to trusted root
      - Check certificate validity period and revocation status
      - Verify ECDSA signature using sender's public key
      - Extract and process payload if signature valid
      - Reject message and log if verification fails

  privacy_analysis:
    description: Analyze V2X system for privacy vulnerabilities
    steps:
      - Review pseudonym change strategies (location tracking risk)
      - Analyze message patterns for unique identifiers
      - Check for information leakage in messages
      - Evaluate correlation attacks (linking pseudonyms)
