FCS_CKM_EXT.4 Cryptographic key zeroization

Hierarchical to: No other components

Dependencies: [FDP_ITC.1 Import of user data without security attributes, or

FDP_ITC.2 Import of user data with security attributes, or FCS_CKM.1 Cryptographic

key generation]

FCS_CKM_EXT.4.1 The TSF shall zeroize all plaintext secret and private cryptographic keys and

CSPs when no longer required.

5.1.3 Cryptographic operation: random bit generation (FCS_RBG)

Family behaviour

This family is added to the class FCS. This family deals with generation of random bit streams in support

of cryptographic operations

Component levelling

FCS_RBG_EXT.1 requires generation of random bits in accordance with a selected standard.

Management: FCS_RBG_EXT.1

There are no management activities foreseen.

Audit: FCS_RBG_EXT.1

The following actions should be auditable if FAU_GEN Security audit data generation is included in the

PP/ST:

a) Minimal: Failure of the activity.

FCS_RBG_EXT.1 Cryptographic operation: random bit generation

Hierarchical to: No other components

Dependencies: No dependencies

FCS_RBG_EXT.1.1 The TSF shall perform all random bit generation (RBG) services in accordance

with [selection, choose one of: NIST Special Publication 800-90 using [selection:

Hash_DRBG (any), HMAC_DRBG (any), CTR_DRBG (AES), Dual_EC_DRBG (any)];

FIPS Pub 140-2 Annex C: X9.31 Appendix 2.4 using AES] seeded by an entropy

source that accumulated entropy from [selection: a software-based noise source, a

TSF-hardware-based noise source].
