The Adaptive Multicast Data Origin Authentication Protocol
Most multicast data origin authentication schemes work under the fixed parameters without taking the problem of changeable network environment into account.However,the network conditions will obviously influence the efficiency of a protocol such as the time delay and the overhead considering the packet loss rate or something else.So adjusting the parameters adaptively to achieve the ideal state with the dynamic network is necessary.To achieve a high authentication rate and adapt to the changeable and unstable network environment,we proposed a multicast data origin authentication protocol which is adaptive depending on the packet error rates as well as the time delay,and is robust against the packet loss and injection.Our model can estimate a more appropriate packet error rate and make the time delay lower according to the feedback values got from the receivers using the Markov chain so that it can be adaptive.What’s more,the IDA (Information Dispersal Algorithm) and the Merkle HASH tree are also combined to resist the packet loss or attack.This strategy is especially efficient in terms of not only the adaptation of dynamic network but also the shortcut of overhead and delay,because the reliable intelligent algorithm is included in and only the necessary parts are involved in to authenticate.
