Encompassing one of the most widely-used and rich set of cryptographic algorithms as well as secure communications protocols, RSA BSAFE software is a set of complementary security products relied on by developers and manufacturers worldwide. The RSA BSAFE Crypto-J software library relies on the JCM library. It includes a wide range of data encryption and signing algorithms, including AES, Triple-DES, the RSA Public Key Cryptosystem, the Elliptic Curve Cryptosystem, DSA, and the SHA-1, SHA-2 and SHA-3 message digest routines. Its software libraries, sample code and complete standards-based implementation enable near-universal interoperability for your networked and e-business applications. 1.2 Module Characteristics The JCM is classified as a FIPS 140-2 multi-chip standalone module. As such, the JCM is tested on particular operating systems and computer platforms. The cryptographic boundary includes the JCM running on selected platforms that are running selected operating systems. The JCM is validated for FIPS 140-2 Security Level 1 requirements. The Cryptographic Module 5 RSA BSAFE Crypto-J JSAFE and JCE Software Module 6.2.5 Security Policy Level 1 The following table lists the certification levels sought for the JCM for each section of the FIPS 140-2 specification. The JCM is packaged in a Java Archive (JAR) file containing all the code for the module. The JCM API of the module is provided in the jcmFIPS-6.2.5.jar and jcmandroidfips-6.2.5.jar files. 1.2.1 Laboratory Validated Operating Environments For FIPS 140-2 validation, the JCM is tested by an accredited FIPS 140-2 testing laboratory on the following operating environments: • Google® ART™ 8.0 on Google Android™ 8.0 ARM® v8 (64-bit) running on Samsung™ Galaxy S9™ with a Qualcomm® Snapdragon™ 845 processor • Oracle® JRE 8.0 on Microsoft® Windows Server® 2016 (64-bit) running on Dell™ PowerEdge™ T130 with an Intel® Xeon® E3 processor • OpenJDK 8.0 on CentOS 7.6 (64-bit) running on Dell PowerEdge R710 with an Intel Xeon E5 processor.

The Cryptographic Module 9 RSA BSAFE Crypto-J JSAFE and JCE Software Module 6.2.5 Security Policy Level 1 1.3 Module Interfaces As a multi-chip standalone module, the physical interface to the JCM consists of a keyboard, mouse, monitor, serial ports and network adapters. The underlying logical interface to the module is the API, documented in the relevant API Javadoc. The module provides the following four logical interfaces that have been designed within the module where input and output are indicated from the perspective of the module: • Control In - the invocation of all methods, the function and API names • Data In - input arguments to all constructors and methods specifying input parameters • Data Out - modified input arguments, those passed by reference, and return values for all constructors and methods modifying input arguments and returning values • Status Out - information returned by the methods and any exceptions thrown by constructors and methods. This is shown in the following diagram.

As allowed by FIPS 140-2, the JCM does not require user identification or authentication for these roles. 1.4.1 Crypto Officer Role The Crypto Officer is responsible for installing and loading the module. Once the module has been installed and is operational, an operator can assume the Crypto Officer Role by constructing a com.rsa.crypto.FIPS140Context object by invoking the ModuleConfig.getFIPS140Context(int mode, int role) method with a role argument of com.rsa.crypto.FIPS140Context.ROLE_CRYPTO_OFFICER. The Services section provides a list of services available to the Crypto Officer Role. 1.4.2 Crypto User Role An operator can assume the Crypto User Role by constructing a com.rsa.crypto.FIPS140Context object by invoking the ModuleConfig.getFIPS140Context(int mode, int role) method with a role argument of com.rsa.crypto.FIPS140Context.ROLE_USER. The Services section provides a list of services available to the Crypto User Role. The Cryptographic Module 11 RSA BSAFE Crypto-J JSAFE and JCE Software Module 6.2.5 Security Policy Level 1 1.4.3 Services The JCM provides services which are available for both FIPS 140-2 and non-FIPS 140-2 usage. For a list of FIPS 140-2 approved and FIPS 140-2 allowed algorithms, see Table 5. The following table lists the un-authenticated services provided by the JCM which may be used by either Role, in either the FIPS or non-FIPS mode, in terms of the module interface. For each interface, lists of algorithms that are allowed and not allowed when operating the module in a FIPS 140-2 compliant way are specified.

In the FIPS-Approved mode, RSA keys can only be generated using the Approved 186-4 RSA key generation method. The module also employs a FIPS-Approved AES Counter-mode DRBG (AES-128-CTR DRBG) for generating asymmetric and symmetric keys used in algorithms such as AES, Triple-DES, RSA, DSA, DH and ECC. 1.5.2 Key Protection All key data resides in internally allocated data structures and can only be output using the JCM API. The operating system and the JRE safeguards memory and process space from unauthorized access. 1.5.3 Key Zeroization The module stores all its keys and Critical Security Parameters (CSPs) in volatile memory. Users can ensure CSPs are properly zeroized by making use of the .clearSensitiveData() method. All of the module’s keys and CSPs are zeroizable. The module operator must zeroize all keys before switching from an approved FIPS 140-2 mode to non-FIPS 140-2 approved mode. For more information about clearing CSPs, see the relevant API Javadoc. 1.5.4 Key Storage The JCM does not provide long-term cryptographic key storage. Storage of keys is the responsibility of the JCM user. The Crypto User and Crypto Officer roles have equal and complete access to all keys and CSPs. The following table shows how the storage of keys and CSPs are handled.

The Cryptographic Module 27 RSA BSAFE Crypto-J JSAFE and JCE Software Module 6.2.5 Security Policy Level 1 1.7 Self-tests The module performs power-up and conditional self-tests to ensure proper operation. If the power-up self-test fails, the module is disabled and throws a SecurityException. The module cannot be used within the current JVM. If the conditional self-test fails, the module throws a SecurityException and aborts the operation. A conditional self-test failure does NOT disable the module. 1.7.1 Power-up Self-tests Power-up self-tests are executed automatically when the module is loaded into memory. The power-up self-tests include the FIPS 140-2 required Software Integrity Test and a set of Cryptographic Algorithms tests. The Software Integrity Test is comprised of an HMAC-SHA1 verification of the files listed in fips140/module.files. The following Cryptographic Algorithm tests are implemented in the module: • AES Decrypt KAT • AES Encrypt KAT • AES/CCM Decrypt KAT • AES/CCM Encrypt KAT • AES/GCM Decrypt KAT • AES/GCM Encrypt KAT • CMAC KAT • CTR DRBG KAT • Diffie-Hellman KAT • DSA Sign/Verify Test • EC Diffie-Hellman KAT • ECDSA Sign/Verify Test • Hash DRBG KAT • HKDF KAT • HMAC DRBG KAT • KDFTLS10 KAT • KDFTLS12 SHA-256 KAT • RSA Signature Generation KAT • RSA Signature Verification KAT • SHA3-512 KAT • SHA-512 KAT • SHAKE256 KAT • Triple-DES Decrypt KAT • Triple-DES Encrypt KAT. 28 The Cryptographic Module RSA BSAFE Crypto-J JSAFE and JCE Software Module 6.2.5 Security Policy Level 1 By default, all Cryptographic Algorithm tests are run at power-up. However, if configured to do so, the module will run all of the power-up self-tests when first loaded in an operational environment, and run only the Software Integrity Test on subsequent restarts. 1.7.2 Conditional Self-tests The module performs two conditional self-tests: • Pair-wise Consistency Tests each time the module generates a DSA, DH, RSA or EC public/private key pair. • Continuous RNG (CRNG) Test each time the module produces random data, as per the FIPS 140-2 standard. The CRNG test is performed on all approved and non-approved PRNGs (HMAC DRBG, HASH DRBG, CTR DRBG, FIPS186 PRNG, non-approved entropy source). 1.7.3 Mitigation of Other Attacks RSA, EC, DSA and DH key operations implement blinding by default. Blinding is a reversible way of modifying the input data, so as to make the operations immune to timing attacks. Blinding has no effect on the algorithm other than to mitigate attacks on the algorithm. RSA, EC, DSA and DH blinding is implemented through blinding modes, for which the following options are available: • Blinding mode off • Blinding mode with no update, where the blinding value is squared for each operation. For other types of timing attacks the module implements time invariant comparisons and operations, for example, PKCS #1 unpadding, HMAC verify, and RSA verify. RSA signing operations implement a verification step after private key operations. This verification step, which has no effect on the signature algorithm, is in place to prevent potential faults in optimized Chinese Remainder Theorem (CRT) implementations. For more information, see Modulus Fault Attacks Against RSA-CRT Signatures. Secure Operation of the Module 29 RSA BSAFE Crypto-J JSAFE and JCE Software Module 6.2.5 Security Policy Level 1 2 Secure Operation of the Module The following guidance must be followed in order to operate the module in a FIPS 140-2 mode of operation, in conformance with FIPS 140-2 requirements. Note: The module operates as a Validated Cryptographic Module only when the rules for secure operation are followed. 2.1 Module Configuration To operate the module in compliance with FIPS 140-2 Level 1 requirements, the module must be loaded using the following method: com.rsa.crypto.jcm.ModuleLoader.load() The ModuleLoader.load() method extracts arguments from the com.rsa.cryptoj.jcm.JavaModuleProperties class, which is created using the com.rsa.cryptoj.jcm.CryptoJModulePropertiesFactory class. The following arguments are extracted: – The module jar file. – The security level, specified as the constant ModuleConfig.LEVEL_1. This should have a value of 1. – An optional SelfTestEventListener to use for logging power-up self-test events. – An optional java.util.concurrent.ExecutorService used for running the power-up self-tests. – An optional File for reading and writing the status of the algorithm power-up self-tests. Using the specified securityLevel ensures that the module is loaded for use in a FIPS 140-2 Level 1 compliant way. Once the load method has been successfully called, the module is operational. 2.2 Security Roles, Services and Authentication Operation To assume a role once the module is operational, construct a FIPS140Context object for the desired role using the FIPS140Context.getFIPS140Context(int mode, int role) method. This object can then be used to perform cryptographic operations using the module. The mode argument must be the value FIPS140Context.MODE_FIPS140. To retrieve the current JCM FIPS 140-2 mode, call FIPS140Context.getMode(). 30 Secure Operation of the Module RSA BSAFE Crypto-J JSAFE and JCE Software Module 6.2.5 Security Policy Level 1 The available role values are the constants FIPS140Context.ROLE_CRYPTO_OFFICER and FIPS140Context.ROLE_USER. No role authentication is required for operation of the module in Security Level 1 mode. When in Security Level 1 mode, invocation of methods which are particular to Security Level 2 Roles, Services and Authentication will result in an error. 2.3 Crypto User Guidance This section provides guidance to the module user to ensure that the module is used in a FIPS 140-2 compliant way. Section 2.3.1 provides algorithm-specific guidance. The requirements listed in this section are not enforced by the module and must be ensured by the module user. Section 2.3.2 provides guidance on obtaining assurances for Digital Signature Applications. Section 2.3.3 provides guidance on obtaining assurances for Key Agreement Applications. Section 2.3.4 provides guidance on obtaining assurances for Key Transport Applications. Section 2.3.5 provides guidance on the entropy requirements for secure key generation. Section 2.3.6 provides information about the minimum length of passwords. Section 2.3.7 provides general crypto user guidance. 2.3.1 Crypto User Guidance on Algorithms • The Crypto User must only use algorithms approved for use in a FIPS 140-2 mode of operation, as listed in Table 5. • Only FIPS 140-2 Approved DRBGs may be used for generation of keys (asymmetric and symmetric). • When using an approved DRBG, the number of bytes of seed key input must be equivalent to or greater than the security strength of the keys the caller wishes to generate. For example, a 256-bit or higher seed key input when generating 256-bit AES keys. • When using an Approved DRBG to generate keys or DSA parameters, the requested DRBG must have a security strength at least as great as the security strength of the key being generated. That means that an Approved DRBG with an appropriate strength must be used. For more information on requesting the DRBG security strength, see the relevant API Javadoc. • Since the module does not modify the output of an Approved DRBG, any generated symmetric keys or seed values are created directly from the output of the Approved DRBG. • FIPS 186-2 RNG is not to be used in an approved FIPS 140-2 mode of operation. Secure Operation of the Module 31 RSA BSAFE Crypto-J JSAFE and JCE Software Module 6.2.5 Security Policy Level 1 • In case the power to the module is lost and then restored, the key used for the AES GCM encryption/decryption shall be re-distributed. • When generating key pairs using the KeyPairGenerator object, the generate(boolean pairwiseConsistency) method must not be invoked with an argument of false. Use of the no-argument generate() method is recommended. • When using GCM feedback mode for AES symmetric encryption, the authentication tag length and authenticated data length may be specified as input parameters, but the full IV must not be specified. It must be generated depending on whether the AES-GCM cipher provided by the module is being used as the cipher implementation in the TLS protocol or for symmetric encryption purposes other than TLS. • The AES-GCM cipher, when used for symmetric encryption purposes other than TLS, must use an IV in one of the two possible ways, to comply with SP 800-38D: – allow the module to generate the IV deterministically by not supplying any IV parameters during cipher initialization. The generated 96-bit (12-byte) IV consists of a 32-bit fixed field followed by a 64-bit invocation field where • the fixed field bytes are derived from the module name, version information and memory address of a Java class within the module • the invocation field is a 64-bit counter that is initialized, on module startup, to a value consisting of the 42 bits of current time, as milliseconds since Epoch, followed by 22 bits of zero. This counter value is incremented by one each time a new IV is requested. By using the current time to prefix the counter start value, in the event of module restart, the counter will be ahead of any previous module states, ensuring that IV values cannot be reused. The module user must ensure the system time is valid to prevent repetition of IVs. – generate at least 12 bytes of IV using an Approved DRBG, and input the IV to the cipher at initialization time using the RAW_IV parameter. • The AES-GCM cipher used for the TLS protocol as the cipher implementation complies with SP 800-52 and is compatible with RFC 5288 with the following conditions: – The IV is configured as follows: • The four-byte salt derived from the TLS handshake process is input using the parameter PARTIAL_IV during cipher initialization. This is used as the first four bytes of IV. This 32-bit part of the IV is also referred to as the nonce value in FIPS 140-2 IG A.5 and is positioned in the name field of the IV as required in FIPS 140-2 IG A.5 Scenario 3. • The remaining eight bytes of IV, referred to as nonce_explicit in RFC 5288, are generated deterministically by the module using the 64-bit counter used for the invocation field described above. 32 Secure Operation of the Module RSA BSAFE Crypto-J JSAFE and JCE Software Module 6.2.5 Security Policy Level 1 • When the 64-bit counter exhausts the maximum number of possible values for a given session key, the module will throw a SecurityException. Whichever party, the client or the server, that encounters this condition must trigger a handshake to establish a new encryption key. – The TLS session is aborted if the keys for the client and server negotiated in the handshake process, client_write_key and server_write_key, are identical. • For RSASSA-PSS: If nLen is 1024 bits, and the output length of the approved hash function output block is 512 bits, then the length of the salt (sLen) shall be 0<=sLen<=hLen - 2 Otherwise, the length of the salt shall be 0 <=sLen<=hLen where hLen is the length of the hash function output block (in bytes or octets). • EC key pairs must have named curve domain parameters from the set of NIST-recommended named curves: P-224, P-256, P-384, P-521, B-233, B-283, B-409, B-571, K-233, K-283, K-409, and K-571. Named curves P192, B163, and K163 are allowed for legacy-use. The domain parameters can be specified by name or can be explicitly defined. • EC Diffie-Hellman primitives must use curve domain parameters from the set of NIST recommended named curves listed above. The domain parameters can be specified by name, or can be explicitly defined. Using the NIST-recommended curves, the computed Diffie-Hellman shared secret provides between 112 bits and 256 bits of security. • When using DSA key pair generation and signature generation or DH key pair generation and key agreement, the domain parameters must have prime P length (PRIME_LEN) and subprime Q length (SUBPRIME_LEN) within the set of acceptable pair sets (PRIME_LEN, SUBPRIME_LEN): (2048, 224), (2048, 256) or (3072, 256). • When generating DSA and DH domain parameters, generation shall comply with FIPS 186-4 by specifying the algorithm string “DSA” when creating the AlgParameterGenerator object. Additionally: – The PRIME_LEN and SUBPRIME_LEN must be from a set of acceptable pair set as stated above. – The digest algorithm parameter shall be selected from the set: SHA224, SHA256, SHA384, SHA512. The digest algorithm shall be selected such that the output length is at least as large as the subprime length. That is: • For subprime 224, all four algorithms may be used. • For subprime 256, only SHA256, SHA384, SHA512 may be used. • For RSA digital signature generation, an Approved DRBG must be used. • RSA keys used for signing shall not be used for any other purpose other than digital signatures. • When generating RSA key pairs for signatures or key transport, generation shall comply with the following: – the KEY_TYPE parameter must be omitted or have a value of 0. – the KEY_BITS parameter must have value 2048 or 3072. Secure Operation of the Module 33 RSA BSAFE Crypto-J JSAFE and JCE Software Module 6.2.5 Security Policy Level 1 – the SECURITY_STRENGTH parameter may be input. Acceptable values are: • 112, when used for KEY_BITS of 2048. • 128, when used for KEY_BITS of 3072. – the PUB_EXP value must be an odd number and have a minimum value of 0x10001 (65537). • The length of an RSA key pair for digital signature generation and verification must be 2048 or 3072 bits. For digital signature verification, 1024 bits is allowed for legacy-use. RSA keys shall have a public exponent of at least 65537. • SHA1 is disallowed for the generation of digital signatures. • The key length for an HMAC generation or verification must be equal to or greater than 112 bits. For HMAC verification, a key length greater than or equal to 80 and less than 112 is allowed for legacy-use. Note: JCE MAC APIs do not distinguish between generate and verify, therefore a key length check is not explicitly performed in JCE. • KDFs: – For Single-step KDF: • A FIPS 140-2 approved hash function must be used. – For HKDF: • A FIPS 140-2 approved HMAC must be used. • The extracted key-derivation key must be used solely for the single key-expansion step. For more information see SP 800-56C Rev.1 • The derived key must be used only as a secret key. • The derived key shall not be used as a key stream for a stream cipher. • When selecting an HMAC hash, the output block size must be equal to or greater than the desired security strength of the derived key. – For TLS 1.0, 1.1 and 1.2 Key Derivation: The TLS 1.0 and 1.1 KDF is allowed only when the following conditions are satisfied: • The KDF is performed in the context of the TLS protocol • SHA-1 and HMAC are as specified in FIPS 180-4 and FIPS 198-1, respectively. The TLS 1.2 KDF, is allowed only when the following conditions are satisfied: • The KDF is performed in the context of the TLS protocol • HMAC is as specified in FIPS 198-1 • P_HASH uses either SHA-256, SHA-384 or SHA-512. For more information, see SP 800-135 Rev. 1. 34 Secure Operation of the Module RSA BSAFE Crypto-J JSAFE and JCE Software Module 6.2.5 Security Policy Level 1 The TLS protocols have not been tested by the CAVP and CMVP. – For PBKDF: • Keys generated using PBKDF shall only be used in data storage applications. • The length of the randomly-generated portion of the salt shall be at least 16 bytes. For more information see nist-sp800-132.pdf. • The iteration count shall be selected as large as possible, a minimum of 10,000 iterations is recommended. • The minimum password length depends on the character set chosen. For examples, see Information on Minimum Password Length. • The maximum key length is (232 -1)*b, where b is the digest size of the hash function. • The key derived using PBKDF can be used as referred to in SP 800-132, Section 5.4, option 1 and 2. • Triple-DES: – For two-key Triple-DES: • The use of two-key Triple-DES for encryption is disallowed. • Decryption using two-key Triple-DES is allowed for legacy-use. The user should determine the risk of accepting the decrypted information when processing more than 220 blocks of data encrypted using two-key Triple-DES. For more information about the use of two-key Triple-DES, see NIST Special Publication 800-131A revision 1 Transitions: Recommendation for Transitioning the Use of Cryptographic Algorithms and Key Lengths. – For three-key Triple-DES: • The use of three-key Triple-DES is approved. • The user is responsible for ensuring the same Triple-DES key has a limit of: • 220 64-bit data block encryptions when keys are generated as part of one of the recognized IETF protocols. • 216 64-bit data block encryptions otherwise. For more information about the use of three-key Triple-DES, see NIST Special Publication 800-67 revision 2: Recommendation for the Triple Data Encryption Algorithm (TDEA) Block Cipher.

The JCM provides the HMAC DRBG, CTR DRBG and Hash DRBG implementations for key generation. When generating secure keys, the DRBG used in key generation must be seeded with a number of bits of entropy that is equal to or greater than the security strength of the key being generated. The entropy supplied to the DRBG is referred to as the DRBG security strength which represents the minimum amount of entropy that should be provided to the DRBG prior to the key generation operation. The following table lists each of the keys that can be generated by the JCM, with the key sizes available, security strengths for each key size and the security strength required to initialize the DRBG. 2.3.6 Information on Minimum Password Length Minimum Password Length: The minimum length (L) of a password generated using a cryptographically secure random password generator to provide a search space of S entries depends on the size (N) of the character set: L= log2S/log2N The following table provides examples for a password used by PBKDF2: S = 4.32 x 1020 Table 10 Generated Key Sizes and Strength Key Type Key Size Security Strength Required DRBG Security Strength AES Key 128, 192, 256 128, 192, 256 128, 192, 256 Triple-DES 3-Key 192 112 112 RSA Key Pair 2048, 3072 112, 128 112, 128 DSA Key Pair 2048, 3072 112, 128 112, 128 EC Key Pair 224, 256, 384, 521 112, 128, 192, 256 112, 128, 192, 256 Character Set N L Case sensitive (a-z, A-Z) 52 13 Case sensitive alpha numeric 62 12 All ASCII printable characters except space 94 11 Secure Operation of the Module 39 RSA BSAFE Crypto-J JSAFE and JCE Software Module 6.2.5 Security Policy Level 1 2.3.7 General Crypto User Guidance JCM users should take care to zeroize CSPs when they are no longer needed.
