There are occasions when some people carry their portable devices to a hotel room or office to hold a short-term conference over wireless networks. This paper designs a user-anonymous and s ort-term Conference Key Distribution System (CKDS) to ensure secure communications over an open channel and to protect the identities of the users. Furthermore, linker-layer routing between the Mobile Hosts (MHs) makes it possible for MHs to directly communicate with one another. Under the random oracle model and the elliptic curve version of the Computational Diffie-Hellman (CDH) assumption, the proposed system is demonstrated to be provably secure against active adversaries. Compared with previously proposed systems, the proposed system is efficient in terms of communication and computational complexity, and is suitable for low-power mobile devices.
