Abstract: Entity authentication is a process of verifying a claimed identity of a network party, but, depending on the application, it entails a number of modalities, such as whether the party is currently active on the network and whether the party is willing to communicate. Combining such modalities in different ways leads to different notions of entity authentication. We propose a new methodology, called the structured intuition (SI), which provides a detailed analysis of entity authentication. There is a single notion of security in our methodology, which is called canonicity, which is a weaker form of message authenticity. As compared to many contemporary analysis techniques, an SI-based analysis provides detailed results regarding the design rationales and entity authentication goals of a protocol.

Keywords: entity authentication; canonicity; dependency graph; structured intuition; authentication protocols; security.
