Abstract: Multicast is a widely applied communication technology. Multicast source authentication is an important problem in multicast security. Especially, it is a big challenge to implement the multicast source authentication in a noisy channel. In order to solve the problem of multicast source authentication in the noisy channel, a chained multicast source authentication technology based on the threshold cryptography is proposed. Firstly, the security assumption and security model of the chained multicast source authentication is provided based on the security requirement of the multicast source authentication and Dolev-Yao model. Then, a new multicast source authentication protocol adapted to the noisy channel is designed by using the threshold secret sharing technology. Finally, the security of the proposed protocol is analyzed. The simulation results show that the multicast source authentication protocol has a good ability to resist packet loss and ensure good communication performance. -
