The advent of conference mobile call demands the security communication between end users. However, currently there is no efficient secure end-to-end protocol exists for conference mobile call. This slows down the steps of conference communication. In this paper a secure end-to-end protocol for remote conference is designed base on previous experts work, which is one-to-one end-to-end protocol. In addition, security analysis from perspectives of confidentiality, authenticity, anonymity, freshness as well as preventing from denial of service (DoS) attack on the protocol is made. At the end, the efficiency of this protocol is discussed.
