We present a fast involutional block cipher optimized for reconfigurable hardware implementations. ICEBERG uses 64-bit text blocks and 128-bit keys. All components are involutional and allow very efficient combinations of encryption/decryption. Hardware implementations of ICEBERG allow to change the key at every clock cycle without any performance loss and its round keys are derived “on-the-fly” in encryption and decryption modes (no storage of round keys is needed). The resulting design offers better hardware efficiency than other recent 128-key-bit block ciphers. Resistance against side-channel cryptanalysis was also considered as a design criteria for ICEBERG.
