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.
