Extended generalized Feistel networks using matrix representation to propose a new lightweight block cipher: Lilliput. While Generalized Feistel Networks (GFNs) have been widely studied in the literature as a building block of a block cipher, we recall in this paper the results of [1] where a unified vision to easily represent them through a matrix representation is proposed. We also introduce a new class of such schemes called Extended Generalized Feistel Networks well suited for cryptographic applications. We instantiate this particular construction into a lightweight block cipher called Lilliput analyzing its security and its hardware performances.
