Ceremonies are a useful tool to establish trust in scenarios where protocols operate. They describe a greater range of issues not taken into account by protocol designers. We take an already-designed protocol and ceremony for a key management protocol operating in a Public-Key Infrastructure environment and test it using a formal method. The ceremonies were analysed to test human peers’ cognition pitfalls using formal methods. The analysis came up with a potential cognitive slip in one early design. This directly affects trust in the protocol.
