Cryptography and security applications make extensive use of random numbers and random bits. However, the generation of random bits is problematic in many practical applications of cryptography. The purpose of American National Standard (ANS) X9.82 is to specify a standard for the design of random bit generators (RBGs) and to provide methods for converting the random bits to random numbers when required. By matching the security requirements of the application using the random bits with the security claims of the RBG generating those bits, an application can safely use the random bits produced by an RBG conforming to this Standard. Part 4 specifies how Approved RBGs shall be constructed, using components from Parts 2 and 3 of the Standard. Part 4 specifies constructions for an RBG, and constructions for building components that are used within those RBG constructions. The information in Part 4 is intended to be combined with the information in the Parts 2 and 3 in order to: Construct an RBG with the required security properties that will be compliant with the Standard, and Verify that an RBG has been constructed in compliance with the Standard. The precise structure, design and development of an RBG is outside the scope of this Standard.

X9.124 Symmetric Key Cryptography for the Financial Services Industry Format Preserving Encryption is a suite of standards consisting of five parts. Part 1 of this standard includes a set of definitions common to all FPE techniques, a security model for FPE block cipher techniques, and a description of the pseudocode language used in defining the mode specified in this document. Part 2 defines requirements for Format Preserving Encryption - Counter Mode (FPCM). FPCM methods encrypt data strings of a specific length and character set into ciphertext of the same length using the same character set and using the equivalent of Counter Mode (CTR) defined in NIST SP38B. Format Preserving Encryption is useful in situations where fixed-format data, such as Primary Account Numbers (PANs) or Social Security Numbers, must be encrypted, but there is a requirement to limit changes to existing communication protocols, database schemata or application code. FPCM is a particularly simple and efficient mechanism to achieve format preserving encryption, which shares many of the strengths and challenges of CTR.
