Tree and Chains United into Multicast Authentication
树链混合组播源认证协议

For multicast communication, authentication is a challenging problem, since it requires that a large number of recipients must verify the data originator. We propose an efficient multicast source authentication protocol called Hybrid Tree and Chains scheme (HTC), which shows more loss resistibility, less communication cost. The HTC scheme is based on combination of single Chain scheme and Hash Tree Chains scheme, and integrates the advantages of both. In this scheme, stream is firstly divided into blocks wi...
