Lars R. Knudsen,

Algorithms and Data Compression

The author presents a new chosen-text attack on the CBC-MAC, which based on DES, is a widely used algorithm to compute a message authentication code (MAC). Using DES with a MAC of size 32 bits, the attack requires ~217 chosen texts and two known texts.
