Resisting Byzantine attack is attracting more and more attention by the majority ofreseachers and becoming an interesting topic in the network security communication problem.When such attack exists in the network, the attacker not only gets some useful information, butalso wants to jamming the normal communications through various means, which adds an errormessage or modifies the normal transmission of information. Therefore, in the large scale ofnetwork environment, data safety transmission is seriously threatened by Byzantine attacker inthe network.To solve the problem fo Byzantine Attack, the traditional techniques, such as dataencryption, hash function and message authentication, has their limitation. Hence, it isnecessary to search a safe and efficient way for data transmission.The core idea of network coding theory is allow the routers to mix multiple inputinformation before coding combination. in order to realize"Max-flow Min-cut"theorem asdetermined maximize network throughput, so as to improve the network channel throughput.But as the work goes further, researchers find that network coding is also an effective methodso keep the security of network data transmission.From the practical point of view, linear network coding for topological structuredynamic changes or larger scale of network, practicability is not strong. Random codingcoefficient even select from a limited domain of linear codes related sources Informationcompression, in order to adapt to topology changes in large or larger network scenarios,. It ishighly practical.In view of the above characteristics, Traditional CBC (Cipher Block Chaining) technologycombined with random network coding is proposed in this paper, construct a secure randomnetwork coding model based on CBC for resisting the Byzantine attacks (S-RBA-RNC) model.Our work mainly can be listed as follows:1. Based on the special situation of data transmission in the network coding, define twoscenarios of the Byzantine attacks and for these two kinds of Byzantine attack situation carriedout a detailed analysis and description.2. CBC technology combined with random network coding, the secure random networkcoding model is proposed for resisting the Byzantine attacks, and whose correctness andsecurity are also proved.3. Security Random Network Coding Model Against Byzantine Attack Based on CBC. Sink are not needed to understand any information about the topology of the network. Thecomputational power of the Byzantine attackers is infinite and the attacker can obtain a codingscheme. Moreover, the secure random network coding scheme is safety when the number of thechannel does not exceed the threshold.4. In final, this scheme can resist the two kinds of Byzantine attack, and comparison withprevious research workers scheme, shows the new scheme have better performance in topology,general ect.
