1 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.
