The Module is intended for use by US Federal agencies and other markets that require a FIPS 140-3 validated Cryptographic Library. The Module is of type software and the module has a Multi-Chip Stand Alone embodiment; the cryptographic boundary is the Java Archive (JAR) file, bc-fips2.0.0.jar. This module is the only software component within the Cryptographic Boundary and the only software component that carries out cryptographic functions covered by FIPS 140-3. Figure 1 shows the logical relationship of the cryptographic module to the other software and hardware components of the computer. The BC classes are executed on the Java Virtual Machine (JVM) using the classes of the Java Runtime Environment (JRE). The JVM is the interface to the computer’s Operating System (OS) that is the interface to the various physical components of the computer.

VMware's BC-FJA (Bouncy Castle FIPS Java API) Table 6: Non-Approved Algorithms Not Allowed in the Approved Mode of Operation

The module design corresponds to the Module security rules. This section documents the security rules enforced by the cryptographic module to implement the security requirements of this FIPS 140-3 Level 1 module.

1. The module shall provide two distinct operator roles: User and Cryptographic Officer.
2. The module does not provide authentication.
3. The operator shall be capable of commanding the module to perform the power up self-tests by cycling power or resetting the module.
4. Power up self-tests do not require any operator action.
5. Data output shall be inhibited during self-tests, zeroization, and error states. Output related to keys and their use is inhibited until the key concerned has been fully generated.
6. Status information does not contain CSPs or sensitive data that if misused could lead to a compromise of the module.
7. There are no restrictions on which keys or CSPs are zeroized by the zeroization service.
8. The module does not support concurrent operators.
9. The module does not have any external input/output devices used for entry/output of data.
10. The module does not enter or output plaintext CSPs from the module’s physical perimeter.
11. The module does not output intermediate key values. HMAC algorithms specified in the Approved Algorithms table produce truncated versions of the HMAC in question. The right most bits are truncated as per the NIST SP 800-107 rev1. When the module is used within the context of Java Security Manager or the system/security property org.bouncycastle.fips.approved_only is set to true, the module will start in approved mode and non-approved services are not accessible in this mode. When the module is not used within the context of Java Security Manager, the module will start in a non-approved mode by default. From non-approved mode to approved mode: It is a combination of granted permission (a) and request to change mode (b): a) org.bouncycastle.crypto.CryptoServicesPermission “changeToApprovedModeEnabled” b) CryptoServicesRegistrar.setApprovedMode(true) The CSPs made available in non-approved mode will not be accessible, once the thread transitions into approved mode. The CSPs generated using the non-approved mode cannot be passed or shared with algorithms operating in approved mode, and vice-versa. This is done by indicating within the class (object), instantiating the key, as being created in an approved mode or non-approved mode. Any attempt by a thread within the execution of the module to use the key in an opposite mode will © 2025 Broadcom Inc. 20

VMware's BC-FJA (Bouncy Castle FIPS Java API) result in an exception being generated by the module. For example, if an RSA private key has been created in either approved or non-approved mode, then any request to access that key will first need to see if the thread making the request is in the same mode. From approved mode to non-approved mode: The module cannot transition from approved mode to non-approved mode. To initiate the module in non-approved mode, either it should not be used in the context of Java Security Manager, or the module should have the permission “org.bouncycastle.crypto.CryptoServicesPermission unapprovedModeEnabled” granted by the Java Security Manager

IVs for GCM can be generated randomly, or via a FipsNonceGenerator. Where an IV is not generated within the module the module supports the importing of GCM IVs. In approved mode, when a GCM IV is generated randomly, the module enforces the use of an approved DRBG in line with Section 8.2.2 of SP 800-38D. In approved mode, when a GCM IV is generated using the FipsNonceGenerator a counter is used as the basis for the nonce and the IV is generated in accordance with TLS protocol. Rollover of the counter in the FipsNonceGenerator will result in an IllegalStateException indicating the FipsNonceGenerator is exhausted and, as per IG C.H, where used for TLS 1.2, rollover will terminate any TLS session in process using the current key and the exception can only be recovered from by using a new handshake and creating a new FipsNonceGenerator. In approved mode, importing a GCM IV for encryption that originates from outside the module is non-conformant. A service indicator for IV usage is provided in the module through Java logging. Setting the logging level to Level.FINE for the named logger “org.bouncycastle.jcajce.provider.BaseCipher” will produce a log message when an IV which may have been produced outside the module and/or not from a compliant source is detected. The log message will be of the standard form including the detail: FINE: Passed in GCM nonce detected: <IV value> where <IV value> is a HEX representation of the IV in use. Setting the logging level to Level.FINER will produce an additional log message for any GCM IV which is used if the previous Level.FINE message is not activated. Log messages in this case will show the detail as: FINER: GCM nonce detected: <IV value> where <IV value> is a HEX representation of the IV in use. 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 AES-GCM Mode falls under: • IG C.H scenario 2: GCM IV is generated randomly, and the module uses an Approved DRBG that is internal to the module’s boundary. The IV length is 96 bits. © 2025 Broadcom Inc. 21

VMware's BC-FJA (Bouncy Castle FIPS Java API) • IG C.H scenario 1 for TLSv1.2 protocol: The module is compatible with TLSv1.2 protocol and supports acceptable AES-GCM ciphersuites from Section 3.3.1 of the SP800-52rev2.

In line with the requirements for SP 800-132, keys generated using the approved PBKDF must only be used for storage applications. Any other use of the approved PBKDF is non-conformant. In approved mode the module enforces that any password used must encode to at least 14 bytes (112 bits) and that the salt is at least 16 bytes (128 bits) long. The iteration count associated with the PBKDF should be as large as practical. As the module is a general-purpose software module, it is not possible to anticipate all the levels of use for the PBKDF, however a user of the module should also note that a password should at least contain enough entropy to be unguessable and also contain enough entropy to reflect the security strength required for the key being generated. In the event a password encoding is simply based on ASCII a 14 byte password is unlikely to contain sufficient entropy for most purposes as the standard set of printable characters only allows for as much as 6 bits of entropy per byte, giving a password which for the case of 14 bytes, yields a key that has been generated using 14 * 6 bits, giving only 84 bits of security, well below what is required for a key with the same level of hardness as a 112 bit one. Users are referred to Appendix A, “Security Considerations” of SP 800-132 for further information on password, salt, and iteration count selection. The iteration count value is provided by the user – and should be appropriate to the way the algorithm is being used (the memory hard augmentation of PBKDF provided by SCRYPT uses an iteration count of 1), for straight PBKDF with no memory hard support, the iteration count provided by the user should be at point where the maximum cost bearable by the user carrying out the key derivation in the normal course of usage. To ensure sufficient whitening of the password in both cases, the module enforces a salt size of 128 bits in approved-only mode. For users interested in introducing memory hardness as a layer on top of the PBKDF the script augmentation to PBDKF based on HMAC SHA-256 (as described in RFC 7914) is also available.

The cSHAKE algorithm offers to input string for customizing the output of the cSHAKE function, the Function-Name input (N) and the Customization String (S). The Function-Name input (N) is reserved for values specified by NIST and should only be set to the appropriate NIST specified value. Any other use of N is non-conformant. The Customization String (S) is available to allow users to customize the cSHAKE function as they wish. The length of S is limited to the available size of a byte array in the JVM running the module. © 2025 Broadcom Inc. 22

The module supports both FF1 and, in non-approved mode, FF3-1 format preserving encryption. Below shows the parameter constraints applicable to the module’s implementation.

Note: only FF1 should be used in approved mode.

The module performs Cryptographic Key Generation in conformance to FIPS 140-3 IG D.H. The CKG for symmetric keys and seeds used for generating asymmetric keys is performed as per Section 4 of the SP800-133r2 and compliant with FIPS 186-4 and SP800-90Arev1 for DRBG. The seed used in asymmetric key generation is the direct output of SP800-90Arev1 DRBG.

The VMware’s BC-FJA (Bouncy Castle FIPS Java API) Module is a software module, and therefore, control of the physical ports is outside of the module’s scope. The module does provide a set of logical interfaces which are mapped to the following FIPS 140-3 defined logical interfaces: data input, data output, control input, status output, and power. When the module performs selftests, is in an error state, is generating keys, or performing zeroization, the module prevents all output on the logical data output interface as only the thread performing the operation has access to the data. The module is single-threaded, and in an error state, the module does not return any output data, only an error value. The module does not implement control output interface. The mapping of the FIPS 140-3 logical interfaces to the module is described in Table 7. © 2025 Broadcom Inc. 23

VMware's BC-FJA (Bouncy Castle FIPS Java API) Table 7: Ports and Interfaces

The jar file representing the module needs to be installed in a JVM’s class path in a manner appropriate to its use in applications running on the JVM. Functionality in the module is provided in two ways. At the lowest level there are distinct classes that provide access to the approved and non-approved services provided by the module. A more abstract level of access can also be gained using strings providing operation names passed into the module’s Java cryptography provider through the APIs described in the Java Cryptography Architecture (JCA) and the Java Cryptography Extension (JCE). When the module is being used in approved mode, classes providing implementations of algorithms which are not approved, or allowed, are explicitly disabled. SSPs such as private and secret keys implement the Destroyable interface. Where appropriate these SSPs can be zeroized on demand by invoking the destroy() method. The return of the destroy() method indicates that the zeroization is complete. Roles, with corresponding service with input and output is specified in Table 8 below: © 2025 Broadcom Inc. 24

VMware's BC-FJA (Bouncy Castle FIPS Java API) Table 8: Roles, Service Commands, Input and Output © 2025 Broadcom Inc. 25

VMware's BC-FJA (Bouncy Castle FIPS Java API)

The module supports two distinct operator roles, User and Cryptographic Officer (CO). The cryptographic module implicitly maps the two roles to the services. A user is considered the owner of the thread that instantiates the module and, therefore, only one concurrent user is allowed. Table

9 lists all operator roles supported by the module. The module does not support a maintenance role

and/or bypass capability. The module does not support authentication. Table 9: Roles and Authentication

Table 10 lists the services and a description of each service with the usage and roles. Services in the module are accessed via the public APIs of the Jar file. The ability of a thread to invoke non-approved services depends on whether it has been registered with the module as approved mode only. In approved only mode no non-approved services are accessible. In the presence of a Java SecurityManager approved mode services specific to a context, such as DSA and ECDSA for use in TLS, require specific permissions to be configured in the JVM configuration by the Cryptographic Officer or User. In the absence of a Java SecurityManager specific services related to protocols such as TLS are available, however must only be used in relation to those protocols. © 2025 Broadcom Inc. 26

The Module type is software. The module has a Multi-Chip Stand Alone embodiment; the cryptographic boundary is the Java Archive (JAR) file, bc-fips-2.0.0.jar. Each time the module is powered up, it runs the pre-operational tests to ensure that the integrity of the module has been maintained. Self–tests are available on demand by power cycling the module. The integrity is verified using HMAC-SHA2-256. The HMAC of the module JAR file excluding directories and metadata is calculated and compared to the expected value embedded within the module’s properties. If the calculated value does not match the expected value, the module raises an error and fails to load. The integrity test can be performed on demand by power cycling the host platform. CASTs are preformed prior to the first use of services related to the test target. CASTs also run periodically on service invocation. Initial CAST self–tests are available on demand by power cycling the module and then invoking the service related to the test target.

The module operates in a modifiable operational environment under the FIPS 140-3 definitions. The module runs on a GPC running one of the operating systems specified in the approved operational environment list in Table 2. 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 within the process space of the Java Virtual Machine. The module optionally uses the Java Security Manager and starts in approved mode by default when used with the Java Security Manager.

The module makes use of the JVM's configured SecureRandom entropy source to provide entropy when required. The module will request entropy as appropriate to the security strength and seeding configuration for the DRBG that is using it and for the default DRBG will request a minimum of

256 bits of entropy. In approved mode the minimum amount of entropy that can be requested by a

DRBG is 112 bits. The module will wait until the SecureRandom.generateSeed() returns the requested amount of entropy, blocking if necessary. The JVMs entropy source can be configured through setting the security property: securerandom.strongAlgorithms in the JVM's java.security file.

In the presence of a Java SecurityManager approved mode services specific to a context, such as DSA and ECDSA for use in TLS, require specific policy permissions to be configured in the JVM configuration by the Cryptographic Officer or User. The SecurityManager can also be used to restrict the ability of particular code bases to examine CSPs. See Section 6.3 for further advice. © 2025 Broadcom Inc. 35

Usage

VMware's BC-FJA (Bouncy Castle FIPS Java API) In the absence of a Java SecurityManager specific services related to protocols such as TLS are available, however must only be used in relation to those protocols.

In default operation the module will start with all algorithms and services enabled. If the module detects that the system property org.bouncycastle.fips.approved_only is set to true the module will start in approved mode and non-approved mode functionality will not be available. If the underlying JVM is running with a Java Security Manager installed the module will be running in approved mode with secret and private key export disabled. When the module is not used within the context of the Java Security Manager, it will start by default in the non-approved mode. Use of the module with a Java Security manager requires the setting of some basic permissions to allow the module HMAC-SHA-256 software integrity test to take place as well as to allow the module itself to examine secret and private keys. The basic permissions required for the module to operate correctly with a Java Security manager are indicated by a Y: Available Java Permissions RuntimePermission                    “getProtectionDomain”                         Y        Allows checksum to be carried out on jar.

The JVM's entropy source is checked according to SP 800-90B, Section 4.4 using the suggest C values for the Repetition Count Test (Section 4.4.1) and the Adaptive Proportion Test (Section 4.4.2) by default. These values can also be configured by the Cryptographic Officer using the security property: “org.bouncycastle.entropy.factors” which takes a comma separated list of C values, one for 4.4.1 and one for 4.4.2, and a value of H.

Source A user can instantiate the default Approved DRBG for the module explicitly by using SecureRandom.getInstance("DEFAULT", "BCFIPS"), or by using a BouncyCastleFipsProvider object instead of the provider name as appropriate. This will seed the Approved DRBG from the live entropy source of the JVM with a number of bits of entropy appropriate to the security strength of the default Approved DRBG configured for the module. The JVM's entropy source is checked according to SP 800-90B, Section 4.4 using the suggest C values for the Repetition Count Test (Section 4.4.1) and the Adaptive Proportion Test (Section 4.4.2). These values can also be configured by the user using the security property: “org.bouncycastle.entropy.factors” which takes a comma separated list of C values, one for 4.4.1 and one for 4.4.2, and a value of H. For the default the property would be set as org.bouncycastle.entropy.factors: 4, 13, 8.0 in the java.security property file. An additional option is available using the Approved Hash_DRBG and the process outlined in SP-

800 90A, Section 8.6.5. This can be turned on by following the instructions in Section 2.3 of the

User Guide. The two DRBGs are instantiated in a chain as a "Source DRBG" to seed the "Target DRBG" in accordance with Section 7 of Draft NIST SP 800-90C, where the Target DRBG is the default Approved DRBG used by the module. The initial seed and the subsequent reseeds for the DRBG chain come from the live entropy source configured for the JVM. The DRBG chain will reseed automatically by pausing for 20 requests (which will usually equate to 5120 bytes). An entropy gathering thread reseeds the DRBG chain when it has gathered sufficient entropy (currently 256 bits) from the live entropy source. Once reseeded, the request counter is reset and the reseed process begins again. © 2025 Broadcom Inc. 37

VMware's BC-FJA (Bouncy Castle FIPS Java API) The “Source DRBG” in the chain is internal to the module and inaccessible to the user to ensure it is only used for generating seeds for the default Approved DRBG of the module. The user shall ensure that the entropy source is configured per Section 6.1 this Security Policy and will block, or fail, if it is unable to provide the amount of entropy requested.

CASTs are performed prior to the first use of services related to the test target. CASTs also run periodically on service invocation. Initial CAST self–tests are available on demand by power cycling the module and then invoking the service related to the test target.

Each time the module is powered up, it performs the pre-operational self-tests to confirm that sensitive data have not been damaged. The pre-operational tests include the Software Integrity test, which verifies the module using HMAC-SHA2-256, and the HMAC and SHS Conditional Cryptographic Algorithm Self-Tests (CAST) which are run prior to the Software Integrity test to ensure the correctness of the HMAC used. Pre-operational self–tests are available on demand by power cycling the module.

The module performs conditional self-tests when the conditions specified for cryptographic algorithm self-test and pair-wise consistency tests occur. Below are the self-tests implemented: Conditional Cryptographic Algorithm Self-Test:

If any of the above-mentioned self-tests fail, the module enters an error state called “Hard Error” state. Upon entering the error state, the module outputs status by way of an exception. An example exception for AES Encryption failure is mentioned below: “Failed self-test on encryption: AES” The module can be recovered by power cycling the module which results in execution of preoperational self-tests and conditional cryptographic algorithm self-tests. If the tests pass, then the module will be available for use.

Vulnerabilities found in the module will be reported on the National Vulnerability Database, located at https://nvd.nist.gov/. Researchers and users are encouraged to report any security related concerns to feedbackcrypto@bouncycastle.org. A PGP public key can be provided if confidentiality is required around the report. Please find the procedures for secure installation, initialization, startup and operation of the module: The module exists as part of the running JVM as such:

• Secure installation of the module requires the use of the unchanged jar to loaded into a JVM via either the class-path or the module-path as appropriate to the JVM and its usage.
• Initialization of the module will occur on startup of the module by the JVM. The user can trigger initialization by attempting to invoke any service in the module or simply calling FipsStatus.isReady() which will only return true if the module has been successfully initialized.
• Once the JVM has loaded the module and the module has been initialized, the startup phase can be over, and the module is able to provide services.
• Operation of the module consists of calling the various APIs providing services, the module code will make use of the current thread for doing any required CASTs and © 2025 Broadcom Inc. 48

The Module implements basic protections to mitigate against timing based attacks against its internal implementations. There are two counter-measures used. The first is Constant Time Comparisons, which protect the digest and integrity algorithms by strictly avoiding “fast fail” comparison of MACs, signatures, and digests so the time taken to compare a MAC, signature, or digest is constant regardless of whether the comparison passes or fails. The second is made up of Numeric Blinding and decryption/signing verification which both protect the RSA algorithm. Numeric Blinding prevents timing attacks against RSA decryption and signing by providing a random input into the operation which is subsequently eliminated when the result is produced. The random input makes it impossible for a third party observing the private key operation to attempt a timing attack on the operation as they do not have knowledge of the random input and consequently the time taken for the operation tells them nothing about the private value of the RSA key. Decryption/signing verification is carried out by calculating a primitive encryption or signature verification operation after a corresponding decryption or signing operation before the result of the decryption or signing operation is returned. The purpose of this is to protect against Lenstra's CRT attack by verifying the correctness the private key calculations involved. Lenstra's CRT attack takes advantage of undetected errors in the use of RSA private keys with CRT values and, if exploitable, can be used to discover the private value of the RSA key. © 2025 Broadcom Inc. 49
