ABSTRACT:
We revisit the two-party ID-based authenticated key agreement protocol and its variant resistant to key-compromise impersonation due to McCullagh & Barreto, which carries a proof of security in the Bellare & Rogaway (1993) model. In this paper, we demonstrated why both the protocol and its variant are not secure if the adversary is allowed to send a Reveal query to reveal non-partner players who had accepted the same session key (i.e., termed as a key-replicating attack in Krawczyk (2005)). We also demonstrate that both protocols do not achieve the key integrity property due to Janson & Tsudik (1995).
