Abstract

The invention discloses a method for calculating the trust values of wireless Mesh network nodes. The method comprises direct trust value calculation, indirect trust value calculation and comprehensive trust value calculation, wherein the direct trust value calculation is carried out for acquiring the interaction times of different time slices among the nodes and establishing a time sequence according to the obtained data at first, and then predicating the interaction times of the next time slice among the nodes by virtue of three times of an exponential smoothing method, and taking the relative errors of the interaction times predicated values and the actual values as the direct trust values of the nodes; the calculation formula of indirect trust values is obtained in a multi-path trust recommendation mode; comprehensive trust values are obtained by virtue of integrated computation for the direct trust values and the indirect trust values. The invention provides a method for calculating the trust values of the nodes, according to the specific condition of a network, adaptive smoothing factor alpha, credibility threshold value Phi, the value of a direct trust value weight beta are selected, the time attenuation characteristic and objectivity of the trust values are guaranteed, the credibility of the nodes is objectively and accurately described, the computation complexity is low, and the method is suitable for a wireless Mesh network.

Description

technical field [0001] The invention belongs to the technical field of computer information security, and in particular relates to a method for calculating trust values ​​of wireless Mesh network nodes. Background technique [0002] The current measures for wireless network security mainly include security measures based on cryptography and security mechanisms based on trust models. Cryptography technology can better defend against various external attacks, but it cannot effectively defend against the attacks of malicious nodes inside the network; the trust model based on the trust value is studied how to use the network node interaction process in a heterogeneous and uncertain network environment. Various subjective and objective evidences are presented to dynamically evaluate the credibility of other nodes and make decisions that are beneficial to upper-layer applications. The trust model participates in the routing selection and data forwarding of nodes, and can detect a...
