  3. Abstract:
  4. In this paper, we describe an impossible differential property for 2.5 rounds of Safer++. It allows an impossible differential attack on 4 rounds of Safer++. The proposed attack requires 2 23 chosen plaintexts and 2 75 bytes of memory and performs 2 84 4-round Safer++ encryptions. The method developed to attack Safer++ can be applied to other block ciphers in Safer family. 1
