Title
Cryptanalysis of Tso et al.'s ID-based tripartite authenticated key agreement protocol
Abstract
A tripartite authenticated key agreement protocol is generally designed to accommodate the need of three specific entities in communicating over an open network with a shared secret key, which is used to preserve confidentiality and data integrity. Since Joux [6] initiates the development of tripartite key agreement protocol, many prominent tripartite schemes have been proposed subsequently. In 2005, Tso et al. [15] have proposed an ID-based non-interactive tripartite key agreement scheme with k-resilience. Based on this scheme, they have further proposed another one-round tripartite application scheme. Although they claimed that both schemes are efficient and secure, we discover that both schemes are in fact breakable. In this paper, we impose several impersonation attacks on Tso et al.'s schemes in order to highlight their flaws. Subsequently, we propose some applicable enhancements which will not only conquer their defects, but also preserve the security attributes of an ideal key agreement protocol.
