A New Message Authentication Code and Its Security Proof
Wenling Wu · Dianzi xuebao · 2006
The most important tool to protect data integrity is Message Authentication Code(MAC),which is widely used in many kinds of secure systems.With the development of the theory of provable security,the MACs,which have security proof,are the first choice of many people.Based on the constructions of XOR MAC and PMAC,we define a deterministic fully parallelizable block-cipher mode of operation for message authentication-DXOR MAC(Deterministic XOR MAC).We prove its security,quantifying an adversary's forgery probability in terms of the quality of the block cipher as a pseudo-random permutation.
