X9.124 Symmetric Key Cryptography for the Financial Services Industry Format Preserving Encryption is a suite of standards consisting of five parts that defines format-preserving encryption (FPE) methods. 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 5燿efines requirements for using the AES or Triple-DES block cipher to perform FPE using a format-preserving Feistel-based mode known as FF3.1. FF3.1 is part of the FFX family of Feistel-based format preserving encryption methods.

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.

As reporting systems become more complex, differences in data formats can cause considerable difficulty. The BALANCE AND TRANSACTION REPORTING STANDARD establishes a common format for exchanging cash management account data. By establishing an efficient mechanism for communication among multiple parties, the standard facilitates complete, accurate, and timely information reporting, and helps reduce the cost of providing this service. The BTRS Code list standardizes Account Status/Balance, Transaction Summary, and Transaction Detail codes across the industry. Old BAI2 codes were thoroughly evaluated and many were retired because they were outdated, redundant, or ambiguous. The resultant BTRS code set provides for a clearer association to Transaction Detail Codes and a standard map to one Summary Code ?it also provides interoperability with ISO 20022 and SWIFT MT. We expect that this BTRS Code list will adapt to the changing global financial environment and provide this process to request new codes
