FIPS self-tests
To ensure the correct operation of cryptography modules, FIPS provides self-test mechanisms, including
power-up self-test and conditional self-test. You can also trigger a self-test. If the power-up self-test fails,
the card where the self-test process exists reboots. If the conditional self-test fails, the system outputs
self-test failure information.
NOTE:
If a self-test fails, contact H3C Support.

Power-up self-tests
The power-up self-test, also called "known-answer test", examines the availability of FIPS-allowed
cryptographic algorithms. A cryptographic algorithm is run on data for which the correct output is
already known. The calculated output is compared with the known answer. If they are not identical, the
known-answer test fails.
The power-up self-test examines the cryptographic algorithms listed in

Conditional self-tests
A conditional self-test runs when an asymmetrical cryptographic module or a random number generator
module is invoked. Conditional self-tests include the following types:
