Overview - ISO/TS 23374-2:2023 (AVPS Security Integration)
ISO/TS 23374-2:2023 is a technical specification in the Intelligent Transport Systems (ITS) family that defines security means and procedures for Type 3 Automated Valet Parking Systems (AVPS). Building on ISO 23374‑1 (system framework and interfaces), this document focuses on the operation interfaces and management interfaces used between subject vehicles (SV), parking facility equipment (PFE), backends and service components. Its goal is to enable secure, interoperable Level‑4 driverless parking deployments while limiting proliferation of security measures across cooperative, connected and automated mobility (CCAM) systems.
Key topics and technical requirements
- Scope & lifecycle: Security lifecycle considerations for AVPS are described to ensure security is addressed through design, deployment and operation.
- Security requirements for AVPS: High‑level security controls tailored for AVPS Type 3, covering procedural and architectural aspects specific to automated valet parking.
- Secure communications: Requirements addressing confidentiality, integrity, availability and authentication for AVPS communication channels (operation and management interfaces).
- Identifiers & sessions: Use and protection of unique identifiers such as reservation ID, session ID and mission ID for authority handovers and mission management.
- Operational functions: Secure handling of remote vehicle operation, check‑in/check‑out, re‑parking, and remote assistance commands.
- Informative annexes:
- Annex A: communication sequences (message flows)
- Annex B: examples of secure communication protocols using PKI
- Annex C: views on threats and risks relevant to AVPS
- Normative references: Integrates with ISO 23374‑1 and refers to automotive cybersecurity engineering practices such as ISO/SAE 21434.
Practical applications and users
Who benefits and uses this standard:
- OEMs and Tier‑1 suppliers designing vehicle subsystems for automated valet parking.
- Parking facility operators and integrators deploying AVPS-enabled infrastructure and RSUs.
- System architects and cybersecurity engineers implementing secure operation and management interfaces.
- Service providers and platform developers building user backends, operator backends and vehicle backends.
- Regulators and procurement teams seeking interoperable security baselines for driverless parking solutions.
Practical uses:
- Specifying secure message flows and authentication for vehicle→facility interactions.
- Designing PKI and TLS/DTLS‑based communication stacks for AVPS.
- Performing threat analysis, risk mitigation and lifecycle security planning for integrated parking services.
- Ensuring interoperability across vehicles from multiple manufacturers and diverse parking facilities.
