WebApr 12, 2024 · This type of Feistel structure is easy to implement and has been used in ciphers such as RC6 , HIGHT , and CLEFIA . However, it is important to note that the Type-II GFS has low diffusion properties and requires a larger number of rounds to achieve full diffusion [ 14 , 15 ], meaning all output sub-blocks are affected by all input sub-blocks.
