Power Up Selftests

Power-Up Self-Tests

The module can perform the following power-up self-tests:

Cryptographic algorithm tests

A known-answer test is conducted for all cryptographic functions (e.g., encryption, decryption, authentication, and random number generation) of each Approved cryptographic algorithm implemented by the cryptographic module. (See the power-up self-tests source code.)

RNG	FIPS 182-2 Change Notice 1 Known Answer Test
ECDSA - NIST Curve P-256 (the Extended ECC version of the module also tests Curve K-283)	Single-Round Known Answer Signature Single-Round Known Answer Verification

Note: Cryptographic algorithms whose outputs vary for a given set of inputs (DSA and ECDSA) are tested using a known-answer test. The message digest algorithms have independent known-answer tests.

Random number generator test

See the known-answer test for RNG above.

Software/firmware integrity test

An integrity check is performed on the libraries that contain the NSS cryptographic module. If the check fails, the module immediately enters the Error state.

Critical functions test

No other critical functions tests are performed on power-up.
