Power-Up Self-Tests; Conditional Self-Tests - HP FlexNetwork 10500 Series Security Configuration Manual

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 Hewlett Packard Enterprise Support.

Power-up self-tests

Power-up self-tests include the following types:
•
Known-answer test (KAT)
This 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.
•
Pairwise conditional test (PWCT)
Signature and authentication test—The test is run when a DSA, RSA, or ECDSA
asymmetrical key pair is generated. It uses the private key to sign the specific data, and
then uses the public key to authenticate the signed data. If the authentication is successful,
the test succeeds.
Encryption and decryption test—The test is run when an RSA asymmetrical key pair is
generated. It uses the public key to encrypt a plain text, and then uses the private key to
decrypt the encrypted text. If the decryption is successful, the test succeeds.
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:
