Abstract: In this paper we present the first biclique cryptanalysis of MIBS block cipher and a new biclique cryptanalysis of PRESENT block cipher. These attacks are performed on full-round MIBS-80 and full-round PRESENT-80. Attack on MIBS- 80 uses matching without matrix method and has a data complexity upper bounded by $2^{52}$ chosen plaintext where it reduced security of this cipher about 1 bit. Attack on PRESENT-80 has a data complexity of at most $2^{22}$ chosen plaintexts and computational complexity of $2^{79.37}$ encryptions that both complexities are lower than other cryptanalyses of PRESENT-80 so far.
