This memo specifies an authentication algorithm based on CMAC with the 128-bit Advanced Encryption Standard (AES) . This new authentication algorithm is named AES-CMAC. The purpose of this document is to make th
Since AES-CMAC is based on a symmetric key block cipher, AES, and HMAC is based on a hash function, such as SHA-1, AES-CMAC is appropriate for information systems in which AES is more readily available than a hash function. This memo specifies the authentication algorithm based on CMAC ...

SMB 3.0 introduced the encryption algorithm Advanced Encryption Standard (AES)-cipher-based message authentication code (CMAC). This addition has helped reduce the protocol’s exposure to cybersecurity risks like man-in-the-middle attacks by protecting sensitive data in transit. Should I Use CI...
It uses an in- tegrity group key for protection, employs a 48-bit packet number to detect replays, and calculates an authenticity tag using AES-CMAC. To denote that a frame is encrypted and authenticated we use the following notation: Encnk {·} Here n denotes the packet number being ...
The AES-CMAC Algorithm, https://www.ietf.org/rfc/rfc4493.txt Windows Server 2012 R2: Which version of the SMB protocol (SMB 1.0, SMB 2.0, SMB 2.1, SMB 3.0 or SMB 3.02) are you using? https://blogs.technet.microsoft.com/josebda/2013/10/02/windows-...
The CMAC algorithm accepts as input a secret key and an arbitrary-length message to be authenticated, and outputs a CMAC. The CMAC value protects both a message's data integrity as well as its authenticity, by allowing verifiers (who also possess the secret key) to detect any change in ...
On the other hand, AES-GCM operates as an authenticated encryption algorithm, providing both confidentiality and integrity by using the counter mode for encryption and Galois field multiplication for authentication. It encrypts data and simultaneously computes an authentication tag, offering a combined ...
