Zero-correlation linear attack is a powerful attack of block ciphers, the lower number of rounds (LNR) which no its distinguisher (named zero-correlation linear approximation, ZCLA) exists reflects the ability of a block cipher against the zero-correlation linear attack. However, due to the large search space, showing there are no ZCLAs exist for a given …
