In this paper, we present a security proof for COMET, the underlying mode of operation of COMET AEAD, a round 1 candidate of the NIST Lightweight Standardization Process. We show that COMET-128 is secure up to 264 bytes of data and 2119 offline computations. This validates the security claims of COMET.
