Services financiers — Gestion et sécurité du numéro personnel d'identification (PIN) — Partie 5: Méthodes pour la génération, la modification et la vérification des PIN

Abstract / scope

This document specifies cryptographic methods for:

—     PIN generation;

—     reference PIN change;

—     transaction PIN verification.

These PIN management functions can be implemented using:

—     encryption using an approved algorithm (see Table 1);

—     CMAC using an approved block cipher (see Table 1);

—     HMAC using an approved hash algorithm (see Table 1).

Refer to ISO 9564-1 for basic principles & requirements regarding PIN establishment.
