Abstract

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.

This standard contributes to the following Sustainable Development Goal
