NIST proposes to withdraw ten Federal Information Processing Standards (FIPS). The standards proposed for withdrawal include:

• FIPS 113, Computer Data Authentication, which specifies an algorithm for generating and verifying a Message Authentication Code (MAC). Since the algorithm is based on the Data Encryption Standard, which has been recommended for withdrawal, NIST plans to recommend the use of newer techniques for data authentication based on more secure algorithms.

• FIPS 161-2, 183, 184, 192, and 192-1 which adopt voluntary industry standards for Federal government use. These FIPS are obsolete because they have not been updated to reference current or revised voluntary industry standards.
• FIPS 4-2, 5-2, 6-4, and 10-4 adopt specifications or data standards that are developed and maintained by other federal agencies or by voluntary industry standards organizations. These FIPS have not been updated to reflect the changes and modifications that have been made by the organizations that develop and maintain the specifications and data representations.

Prior to the submission of this proposed withdrawal of FIPS to the Secretary of Commerce for review and approval, NIST invites comments from the public, users, the information technology industry, and Federal, State and local governments government organizations concerning the withdrawal of the FIPS.
