Embodiment Construction
[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0028] refer to figure 1 and figure 2 , an anti-pollution network coding method based on message authentication code and probabilistic key distribution mechanism, including the following process:
[0029] In order to solve the problem of node information being polluted during data transmission, a corresponding multi-source multicast model research scenario is established.
[0030] figure 1 is the multi-source multicast system model, in this figure, s 1 ,s 2 ,...,s k is the source node, t 1 , t 2 ,...,t p For the sink node, there are multiple forwarding nodes. Assuming that the source node is credible, it is necessary to ensure that during the process of sending information from the source node to the forwarding node and from the forwarding node to the sink node, the polluting nodes must be detected and filtered as early as possible, so that the info...

The invention relates to a message authentication code and probability secret key distribution mechanism-based anti-pollution network coding method. The method comprises the following steps: step one, information source node parameter establish; step two, MAV value calculation; and step three, forwarding node and information receiver node message authentication. To be specific, according to the step three, whether the forwarding node and the information receiver node verification message packet is polluted is determined. The MAC value is used for code word authentication in the message; the forwarding node and the information receiver node verify the MAC value of the input message code word based on the secret pair shared with the information source node, and code words for MAC value calculation in the message are obtained; the coding result of the code words is compared with a Hash value in a decryption result; if the coding result is identical with the Hash value, the message packet is not polluted; and otherwise, the packet is determined to be polluted, so that the forwarding node and the information receiver node can detect or filter the polluted message packet as early as possible. According to the invention, on the basis of the message authentication code and probability secret key distribution mechanism in the cryptology, the provided method has the high calculation security and the attack from the message polluter can be effectively dealt with.
