- Abstract
- In 2005, Lee et al. proposed an ID-based 2-party key agreement protocol
between users whose private keys were issued by independent PKGs that
do not share any system parameters. This work was the first kind that assumes
completely independent multiple PKG environment. However, Lee et al. protocol
has a flaw that allows attackers to impersonate others without knowing their
private keys. In this paper, we propose a modification to the protocol of Lee et
al. that prevents impersonation attacks.We also show a simple technique that can
improve the efficiency of tripartite key agreement protocol of Lee et al. We also
provide analysis of the security and efficiency of the proposed protocols.
