Abstract

Proofs are invaluable tools in assuring protocol implementers about the security properties of protocols. However, several instances of undetected flaws in the proofs of protocols (resulting in flawed protocols) undermine the credibility of provably-secure protocols. In this work, we examine several protocols with claimed proofs of security by Boyd & Gonzalez-Nieto (2003), Jakobsson & Pointcheval (2001), and Wong & Chan (2001), and an authenticator by Bellare, Canetti, & Krawczyk (1998). Using these protocols as case studies, we reveal previously unpublished flaws in these protocols and their proofs. We hope our analysis will enable similar mistakes to be avoided in the future.

42 citations in Scopus
Search Google Scholar™
51 citations in Web of Science®

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
