Abstract
A new message authentication code (MAC) algorithm is proposed, which i mproves the popular retail MAC based on the data encryption standard; it has the same complexity, but provides better resistance against key recovery attacks. Ln addition, a new key recovery attack on the retai l MAC is presented, requiring a single known text-MAC pair and 2(56) o nline MAC verifications.
