The performance of cipher based MAC techniques depends on the underlying block cipher that is used to calculate the MAC value. For block cipher based MAC schemes, CBC-MAC/XXTEA has been chosen since it has less energy consumption than AES and RC5 and better security strength than skipjack schem...
This paper provides aunified framework for improvingPRF(pseudorandom function) advantages of several popular MACs (message authentication codes) based on a blockcipher modeled asRP(random permutation). In many known MACs, the inputs of the underlying blockcipher are defined to be some deterministic a...
A system for verifying a cipher-based message authentication code (CMAC), including a reception (RX) module logically residing between a physical layer controller (PHY) and a media access controller (MAC) processor, such that the RX module is configured to receive one or more portions of the ...

This is useful in the case where a random IV was created, or in the context of password-based encryption or decryption, where the IV is derived from a user-supplied password. Returns: the initialization vector in a new buffer, or null if the underlying algorithm does not use an IV, or...

For example, in one embodiment, a single indexed key is used for each packet in a packet based communications system. In this embodiment, the key used for the packet may be updated by various modifications after the encryption process. This might comprise adding the MAC or random nonce used ...
The MAC protects both a message's integrity - by ensuring that a different MAC will be produced if the message has changed - as well as its authenticity - because only someone who knows the secret key could be able to generate a valid MAC. The proposed process incorporates a FIPS approved...
