Biclique attack, is a new cryptanalytic technique which brings new tools from the area of hash functions to the area of block cipher cryptanalysis. Till now, this technique is the only one able to analyze the full-round AES cipher in a single key scenario. In this paper, the authors introduce non-isomorphic biclique attack, a modified version of the original biclique attack. In this paper they obtain isomorphic groups of bicliques, each group contains several non-isomorphic bicliques of different dimensions.
