We observe that the definitions of security in the computational complexity proof models of Bellare & Rogaway (1993) and Canetti & Krawczyk (2001) require two partners in the presence of a malicious adversary to accept the same session key, which we term a key sharing requirement. We then revisit the Bellare--Rogaway three-party key distribution (3PKD) protocol and the Jeong--Katz--Lee two-party authenticated key exchange protocol TS2, which carry claimed proofs of security in the Canetti & Krawczyk (2001) model and the Bellare & Rogaway (1993) model respectively. We reveal previously unpublished flaws in these protocols where we demonstrate that both protocols fail to satisfy the definition of security in the respective models. We present a new 3PKD protocol as an improvement with a proof of security in the Canetti & Krawczyk (2001) model and a simple fix to the specification of protocol TS2. We also identify several variants of the key sharing requirement and present a brief discussion.

Search Google Scholar™

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.
