AES GCM encryption and decryption are used in the context of the TLS protocol version 1.2 (compliant to Scenario 1a in FIPS 140-3 IG C.H). The module is compliant with NIST SP 800-52 and the mechanism for IV generation is compliant with RFC 5288. The module ensures that it is strictly increasing and thus cannot repeat. When the IV exhausts the maximum number of possible values for a given session key, the first party (client or server) to encounter this condition may either trigger a handshake to establish a new encryption key in accordance with RFC 5246 or fail. In either case, the module prevents any IV duplication and thus enforces the security property. The module’s IV is generated internally by the module’s Approved DRBG, which is internal to the module’s boundary. The IV is 96 bits in length per NIST SP 800-38D, Section 8.2.2 and FIPS 140-3 IG C.H scenario 2. The selection of the IV construction method is the responsibility of the user of this cryptographic module. In approved mode, users of the module must not utilize GCM with an externally generated IV. Per IG C.H, in the event module power is lost and restored, the consuming application must ensure that any of its AES-GCM keys used for encryption or decryption are re-distributed. The module implements the KDF TLS 1.2, and other cryptographic primitives used in TLS 1.2, but does not implement the TLS 1.2 protocol itself.

The module allows the use of 1024-bit RSA keys for legacy purposes including signature generation, which is disallowed in Approved mode as per NIST SP800-131Arev2. Therefore, cryptographic operations with the Non-Approved key sizes will result in the module operating in Non-Approved mode. The elliptic curves utilized shall be the validated NIST-recommended curves and shall provide a minimum of 112 bits of encryption strength.

Non-Approved cryptographic algorithms shall not share the same key or CSP as an approved algorithm. As such, Approved algorithms shall not use the keys generated by the module’s Non-Approved key generation methods or the converse.

The module supports two modes of operation: Approved and Non-approved. The module will be in approved mode when all self-tests have completed successfully, and only Approved algorithms are invoked. See Table 4 above for a list of the supported Approved algorithms. The non-Approved mode is entered when a non-Approved algorithm is invoked. See Table 6 for a list of non-Approved algorithms.

3. Cryptographic Module Interfaces The Data Input interface consists of the input parameters of the API functions. The Data Output interface consists of the output parameters of the API functions. The Control Input interface consists of the actual API input parameters. The Status Output interface includes the return values of the API functions. Logical interface Data that passes over port/interface Data Input API input parameters Data Output API output parameters and return values Control Input API input parameters Status Output API return values Table 7 - Ports and Interfaces The module does not implement a power input interface or a control output interface. As a software module, control of the physical ports is outside the module scope. However, when the module is performing self-tests, or is in an error state, all output on the module’s logical data output interfaces is inhibited.

4. Roles, Services, and Authentication

The cryptographic module only implements a Crypto Officer (CO) role. The CO role is implicitly assumed by the entity accessing services implemented by the module. An operator is considered the owner of the thread that instantiates the module and, therefore, only one operator is allowed, and no concurrent operators are allowed.

The module does not support operator authentication.

The Approved services supported by the module and access rights within services accessible over the module’s public interface are listed in the table below: Role Service Input Output CO Symmetric Encryption Plaintext, encryption key Return code, ciphertext CO Symmetric Decryption Ciphertext, decryption key Return code, plaintext CO Keyed Hashing Message, key Return code, Message Authentication Code CO Hashing Message Return code, hash CO Random Bit Generation API call parameters Return code, random bits CO Signature Generation Message, signing key Return code, signature CO Signature Verification Signature, verification key Return code CO Key Transport API call parameters, wrapping key Return code, wrapped key CO Key Agreement API call parameters Return code, shared secret CO TLS Key Derivation API call parameters, TLS pre- Return code, TLS Key master secret CO Key Generation API call parameters Return code, key pair CO Key Verification API call parameters, key pair Return code CO On-Demand Self-Test N/A Return code CO Zeroization N/A N/A CO Show Status API call parameters Return code, status Table 8 - Roles, Service Commands, Input and Output Approved services are listed in Table 9. The SSPs listed in the table indicate the access required using below notation: G = Generate: The module generates or derives the SSP. R = Read: The SSP is read from the module (e.g., the SSP is output). W = Write: The SSP is updated, imported, or written to the module. E = Execute: The module uses the SSP in performing a cryptographic operation. Z = Zeroize: The module zeroizes the SSP.

5. Software/Firmware Security The pre-operational integrity test is performed using HMAC-SHA2-256. The integrity test can be executed on demand by power-cycling the host platform and reloading the module. The module does not support software loading. Please refer to Section 11.1 for instructions on compiling the source code into executable.

The form of the module is a single object file, bcm.o.

6. Operational Environment The module runs on a GPC, which is a modifiable operational environment, running one of the operating systems specified in Table
7. Each approved operating system manages processes and threads in a logically separated manner. The module’s user is considered the owner of the calling application that instantiates the module. No specific security rules, settings or restrictions to the configuration of the operational environment applies to the module. The module is designed to ensure that all the self-tests are initiated automatically when the module is loaded.
8. Physical Security As a software module, the physical security requirements are not applicable.

Entropy sources Minimum number of bits of Details entropy Passive Entropy 112 bits and above Use of a [SP800-90B] compliant entropy source with at least 256 bits of security strength. Entropy is supplied to the Module via callback functions. The callback functions shall return an error if the minimum entropy strength cannot be met. The caveat “No assurance of the minimum strength of generated SSPs (e.g., keys)” is applicable Table 12 - Non-Deterministic Random Number Generation Specification 10. Self-Tests ISO/IEC 19790 requires the module to perform self-tests to ensure the integrity of the module and the correctness of the cryptographic functionality. Some functions also require conditional tests during normal operation of the module. The self-tests can be requested on demand by power cycling the host platform. The module has a single error state, which is called the error state. This state is entered upon failure of a self-test. The module indicates this error state by providing the output status “*** KAT failed” where *** is the algorithm name (example: ECDSA-sign KAT failed). The module can be recovered by terminating execution of the host program and reclamation by the host operating system. The supported tests are listed and described in this section.

Pre-operational self-tests are run upon the initialization of the module and further reboots of the host platform. The CAST (Cryptographic Algorithm Self-Test) for HMAC-SHA2-256 is performed before the integrity test. Self-tests do not require operator intervention to run. If any of the tests fail, the module will not initialize and enter an error state where no services can be accessed. The module implements the following pre-operational self-tests:

• Software Integrity Test (HMAC-SHA2-256)

Conditional Cryptographic Algorithm Self-Tests (CAST) are run prior to the first use of the cryptographic algorithm. CASTs do not require operator intervention to run. If any of the tests fail, the module will enter an error state and no services can be accessed. Public Material
