Abstract

We examine the role of session identifiers (SIDs) in security proofs for key establishment protocols. After reviewing the practical importance of SIDs we use as a case study the three-party server-based key distribution (3PKD) protocol of Bellare and Rogaway, proven secure in 1995. We show incidentally that the partnership function used in the existing security proof is flawed. There seems to be no way to define a SID for the 3PKD protocol that will preserve the proof of security. A small change to the protocol allows a natural definition for a SID and we prove that the new protocol is secure using this SID to define partnering.

Citation countsare 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.
