7/28/2023 0 Comments Bitmessage mac![]() The following table describes the basic definitions necessary to RFC 4493 The AES-CMAC Algorithm June 2006 2. This new authentication algorithm is named AES-CMAC. This memo specifies the authentication algorithm based on CMAC withĪES-128. HMAC is based on a hash function, such as SHA-1, AES-CMAC isĪppropriate for information systems in which AES is more readily Since AES-CMAC is based on a symmetric key block cipher, AES, and Modifications of the data, as well as accidental modifications.ĪES-CMAC achieves a security goal similar to that of HMAC. The data, while CMAC is designed to detect intentional, unauthorized Or an error-detecting code detects only accidental modifications of Of CBC-MAC, and OMAC1 efficiently reduces the key size of XCBC.ĪES-CMAC provides stronger assurance of data integrity than aĬhecksum or an error-detecting code. XCBC efficiently addresses the security deficiencies Improvement of the basic Cipher Block Chaining-Message AuthenticationĬode (CBC-MAC). Submitted by Black and Rogaway, which itself is an Improvement of the eXtended Cipher Block Chaining mode (XCBC) CMAC is equivalent to the One-Key CBC MAC1 (OMAC1) Symmetric key block cipher, such as the Advanced Encryption Standard CMAC is a keyed hash function that is based on a RFC 4493 The AES-CMAC Algorithm June 2006ġ. Purpose of this document is to make the AES-CMAC algorithmĬonveniently available to the Internet Community. This memo specifies an authenticationĪlgorithm based on CMAC with the 128-bit Advanced Encryption Standard (CMAC), which is equivalent to the One-Key CBC MAC1 (OMAC1) submittedīy Iwata and Kurosawa. Recently specified the Cipher-based Message Authentication Code The National Institute of Standards and Technology (NIST) has Distribution of thisĬopyright (C) The Internet Society (2006). Not specify an Internet standard of any kind. This memo provides information for the Internet community. ![]() RFC 4493: The AES-CMAC Algorithm Ĭategory: Informational University of Washington
