CRYPTON: A new 128-bit block cipher


  • 12-round self-invertible cipher with 128-bit block size and key length up to 256 bits.
  • Guaranteed security against existing attacks, such as differential and linear cryptanalysis.
  • High performance in SW: 362 cycles on Pentium III/450MHz (about 150 Mbps).
  • Fast key scheduling: much faster than one-block encryption.
  • Efficiency in HW implementation: a Gbps range with low-cost gate array implementation.
  • Completely royalty-free: it’s put in the public domain.
