what is Biclique Attack?

Biclique Attack

"Biclique attack is a publicly well known single key(symmetric key) attack on AES (Advanced Encryption Standard) cryptanalysis. Biclique attack is a MITM (Men In The Middle) attack variant. And uses biclique (complete Bipartite graph a mathematical concept) technique to increase or extend the number of rounds to decrypt AES encryption."

Biclique is a well known attack which uses MITM(Men In The Middle Attack) technique by extending the overall attempt or rounds power to decrypt AES.The interesting thing is, it uses a mathematical concept called Biclique or complete Bipartite graph to extend the number of MITM attacks to break into AES cryptanalysis.

Biclique attack breaks full AES encryption by using full attempts and ensure to provide computational complexity of the attack is 2^126.1, 2^189.7 and 2^254.4 for AES128, AES192 and AES256, respectively. Becauses this attack uses MITM as a base it has also used to break encryptions and hash functions. It has broken kasumi hash method successfully.
