Abstract

Various authentication and authenticated encryption with associated data (AEAD) notions have been employed in protocol channel security modeling and analysis, occasionally failing to accurately model the intended target. As such, this research provides a clear hierarchy of such notions for authentication, which consequently demonstrate how the connections between authentication guarantees of real-world protocols can be delineated – such as between TLS and 802.11. Generic constructions between authentication as well as AEAD levels are also provided, allowing for ease of analysis and building of authentication protocols at higher level notions based upon basic authentication guarantees.
