==Algorithm== Tiger is based on [[Merkle–Damgård construction]]. The [[one-way compression function]] operates on 64-bit words, maintaining 3 words of state and processing 8 words of data. There are 24 rounds, using a combination of operation mixing with XOR and addition/subtraction, rotates, and [[S-box]] lookups, and a fairly intricate key scheduling algorithm for deriving 24 round keys from the 8 input words. Although fast in software, Tiger's large S-boxes (four S-boxes, each with 256 64-bit entries totaling 8 [[KiB]]) make implementations in hardware or [[microcontroller]]s difficult.{{citation needed|date=April 2020}}
