Observations on COMET

Published

Abstract

This note provides two observations on COMET, a second round candidate of the NIST lightweight cryptography standardization process. The first observation uses a long message to detect the use of weak keys, whereas the second observation focuses on the resistance of COMET against slide attacks. These observations do not invalidate the security claims of the designers
