Sequential message authentication code without random oracles
Message authentication code Sequential aggregate
2014/3/11
Katz et al. provided a generic transform to construct aggregate message authentication codes and imposed a lower bound on the length of one aggregate MAC tag. The lower bound shows that the required t...
Cryptanalysis of a Message Authentication Code due to Cary and Venkatesan
Cryptanalysis Message Authentication Code Cary Venkatesan

We present a cryptanalysis of a MAC proposal at CRYPTO 2003
due to Cary and Venkatesan. Our attacks find collisions for the MAC
and yield MAC forgeries, both faster than a straightforward applicatio...
FRMAC,a Fast Randomized Message Authentication Code
Block Ciphers Message Authentication Codes
2009/3/27
We revisit the randomized approach followed in the design of the RMAC
message authentication code in order to construct a MAC with similar properties, but
based on Wegman-Carter's "-universal hash f...
3C-A Provably Secure Pseudorandom Function and Message Authentication Code.A New mode of operation for Cryptographic Hash Function
3C-A Provably Secure Pseudorandom Function Message Authentication Code Cryptographic Hash Function
2009/3/13
We propose a new cryptographic construction called 3C, which works as a pseudoran-
dom function (PRF), message authentication code (MAC) and cryptographic hash function. The 3C-
construction is obta...
