The Research Of Information Security Based On Multipath Transmission

Wireless sensor networks by sensor nodes of a region sensitive data acquisition and processing, and neighbor nodes to pass data to the target node, through mutual cooperation between the network nodes, thus completing the regional monitoring task [1]. Unattended wireless sensor networks and wireless communication features, the message transfer in the network vulnerable to interference and eavesdropping.Enemy control node, not only the information detected can not be accurate transmission to the target node, but also by the enemy exploited by congestion, denial of service attack on the network, reduce the security of information transmission network and reliability.Therefore, the security of information transmission network to become one of the focus of attention in the process of development of wireless sensor networks.Using multi-path transmission of information in WSN is an effective means to resist attack, but in the existing multi-path routing scheme, due to the different path discovery algorithm, there are some shortages on the program transmission efficiency and the ability to resist attack.On the basis of the analysis of the existing multi-path routing scheme, the authors propose a no cross-branch path-based multi-path routing scheme in WSN. The nodes in the network to find disjoint paths from the source node to a different branch node (the neighbors of sink), to find disjoint paths reach the sink (base station). Disjoint multipath routing based on combined threshold secret security sharing method as well as the transmission of information requirements, decomposition of information processing decryption method to further improve the security of information transmission network Finally Simulation results show that the proposed scheme give lower the probability of attack in the information transmission than current multi-path routing scheme, more effectively ensure the security of information transmission.
