Primary tabs
Reference:
ISO 9564-5:2025
Publication Year:
2025
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.
