%X Today there is a widening in digital technologies and increasing in new multimedia services like: pay-per-view TV, interactive simulations, teleconferencing. So there is an increasing demand for multicast communication. There is a number of security issues in multicast communication directly related to the specific nature of multicast. In this paper, we propose a new scheme for authenticating streamed data delivered in real-time over an insecure network we concentrate on the multicast authentication problem. Important requirements of multicast communication protocols are: to perform authentication in real-time, to resist packet loss to have low communication and computation overheads. In the present paper, a scheme for authenticating multicast data applications is proposed. The proposed protocol can be viewed as an improvement of LAR protocol (proposed by R.Latif et al in Jan 2011) [1]. The modified LAR doesn't assume the group members are honest as in LAR with lower communication overhead.
