摘要:In this paper, we show how to use the novel extended strand space method to verify Kerberos V. First, we formally model novel semantical features in Kerberos V such as timestamps and protocol mixture in this new framework. Second, we apply unsolicited authentication test to prove its secrecy and authentication goals of Kerberos V. Our formalization and proof in this case study have been mechanized using Isabelle/HOL.
