Universal deployment of lightweight block ciphers increase the importance of cryptanalysis of these ciphers. In this paper, we focus on reduced round version of Piccolo-80 as a lightweight block cipher and try to analyze it by zero correlation linear attack. As a result, we proposed a new zero correlation linear attack on 12-round Piccolo-80 without whitening keys with computational complexity of 𝟐𝟓𝟏.𝟒, while memory and data complexities of the attack are equal to 𝟐𝟓𝟖.𝟐 and 𝟐𝟓𝟎, respectively. Also, we proposed an attack on 12-round Piccolo-80 with whitening keys and 13-round Piccolo-80 without whitening keys. To the best of our knowledge, these are the first zero correlation attacks on reduced round variants of Piccolo-80.
