Overview
ISO/IEC 19823-11:2022 specifies conformance test methods for the PRESENT-80 crypto suite as defined in ISO/IEC 29167-11. It defines how to verify that RFID tags and interrogators (readers) using the ISO/IEC 18000 air interfaces correctly implement the mandatory cryptographic functions, protocol elements and conformance parameters that affect interoperability, protocol messaging and nominal values/tolerances.
Key topics and requirements
- Scope of testing: Conformance tests cover all mandatory functions of the PRESENT-80 crypto suite and selected optional features when supported by the device under test (DUT).
- Test approaches:
- By demonstration - laboratory testing (performed by ISO/IEC 17025‑accredited labs) with defined test conditions and test patterns.
- By design - vendor-supplied technical analysis or design evidence accepted in place of laboratory demonstration for certain requirements.
- Protocol and parameters verified:
- Interrogator challenge generation (IChallenge) carried in the TAM1 message.
- Tag behavior on receiving TAM1 (abort incomplete crypto protocols, remain in Initial state).
- Support for AuthMethod=00 and appropriate handling of unsupported RFU values (set “Not Supported” crypto suite error).
- Handling of fields such as E and T (support or rejection with error), Key.KeyID, and KeyLength (L) for selecting PRESENT-80 vs. PRESENT-128.
- Tag generation of a 20‑bit random salt (TRnd) and the use of PRESENT-k encryption to compute a 64‑bit TResponse where applicable.
- Test artifacts: A test map for optional features and a set of Test Patterns 1–4 are used to exercise and record compliance with specific protocol and cryptographic behaviors.
Applications and who uses it
- RFID tag and reader manufacturers - to demonstrate conformity of security implementations (PRESENT‑80) to ISO/IEC 29167‑11.
- Conformance testing laboratories - to execute laboratory tests and issue compliance reports (aligned with ISO/IEC 17025).
- System integrators and product certifiers - to validate interoperability of RFID security features across ISO/IEC 18000 deployments.
- Security architects and compliance officers - to ensure products meet mandated behavior for authentication, key handling and protocol error reporting.
