Overview
ISO/IEC 19823-11:2025 - "Information technology - Conformance test methods for security service crypto suites - Part 11: Crypto suite PRESENT-80" defines conformance test methods for the PRESENT-80 crypto suite as specified in ISO/IEC 29167-11. The second edition (2025) provides procedures to verify that RFID tags and interrogators (air interfaces of the ISO/IEC 18000 series) correctly implement all mandatory crypto functions and selected optional features. The standard is intended for conformance testing in accredited laboratories and complements the ISO/IEC 18047 series for RFID device conformance.
Key topics and requirements
- Scope and applicability
- Applies to RFID tags and interrogators that use ISO/IEC 29167-11 (PRESENT-80) in ISO/IEC 18000 air interfaces.
- Tests cover all mandatory functions; optional features are reported using a test map.
- Test methods
- Two principal verification approaches:
- By demonstration - laboratory tests (ISO/IEC 17025 competence expected) with specified test patterns.
- By design - vendor technical analysis or design evidence for requirements where testing is not necessary.
- Protocol and crypto requirements
- Defines behavior for TAM1/TAM1 response exchange, including Interrogator challenge (IChallenge) generation and Tag handling of TAM1 messages.
- Requires Tag support for an 80‑bit key (Key.ID = 0) for Tag authentication; supports PRESENT-k encryption to compute 64‑bit TResponse values.
- Tag generates a 20‑bit salt (TRnd) and uses Key.KeyID and encryption parameters (KeyLength L, options E and T) with defined error handling for unsupported values.
- Test patterns (Test Pattern 1–4) are referenced for practical verification of parsing, response computation and error conditions.
- Conformance prerequisites
Practical applications and users
- Who uses it:
- RFID tag and reader manufacturers validating PRESENT-80 implementation.
- Conformance and accreditation laboratories performing formal certification testing.
- Security engineers and product integrators ensuring interoperable, standards-compliant cryptographic behavior.
- Procurement and compliance teams specifying validated RFID security for supply chains, asset management, and anti-counterfeiting.
- Practical value:
- Provides reproducible test procedures to assure interoperability and cryptographic correctness.
- Helps reduce field failures related to crypto negotiation, key handling, and protocol errors.
