MacDES: MAC algorithm based on DES
A new message authentication code (MAC) algorithm is proposed, which improves 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 retail MAC is presented,...

| Zusammenfassung: | A new message authentication code (MAC) algorithm is proposed, which improves 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 retail MAC is presented, requiring a single known text-MAC pair and 2(56) online MAC verifications. |
