The NA62 experiment at CERN SPS aims to measure the branching ratio of the ultra-rare kaon decay K+→π+νν with 10% precision, collecting ∼ 100 events, assuming the Standard Model~(SM) branching ratio of 8.4 × 10-11, starting in 2016. The NA62 experiment uses a kaon decay-in-flight technique and is exposed to a 750~MHz high-energy unseparated charged hadron beam, in which kaons are a minor component (6%). Kaon identification is therefore mandatory to reduce the interference of the dominant non-kaon component with the experimental measurements. The NA62 kaon identification system and its performances are presented.
