ISO/IEC 19823-11:2025 PDF

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
  • Devices must first pass relevant ISO/IEC 18047-6 conformance tests before applying ISO/IEC 19823-11 tests.

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.
