A novel authentication protocol for teleconference service is proposed. The main features of the proposed protocol include identity anonymity, one-time PID (pseudonym identity) renewal and location intractability. Identity anonymity is achieved by concealing the real identity of a mobile conferee in a prearranged pseudonym identity. One-time PID renewal mechanism, in which the mobile conferee's PID is frequently updated communicating with the network centre, is introduced to offer location intractability. It is shown that the security has been significantly enhanced, while the computation complexity is similar to the existing one appeared in the literature.
