Embodiment Construction

[0043] A further detailed description of the technical solution of the present invention is given below in conjunction with the accompanying drawings, so that those skilled in the art can understand the solution of the present invention more clearly, but the protection scope of the present invention is not limited thereby.

[0044] For ease of understanding, the principle of resisting black hole node attacks of the present invention is briefly given at first: in the Ad-hoc network, when the route selection mode is adopted, the malicious node adds false available channel information to the received route request packet in the route discovery stage, It is a malicious attack that tricks other nodes into establishing a routing connection with it, and then discards the data packets that need to be forwarded, resulting in data packet loss.

[0045] In order to prevent the black hole node from modifying the information contained in the routing request packet, the present invention inn...

Abstract

The invention discloses a SAODA optimization method capable of effectively fighting against black hole attacks. The technical schemes are as follows: based on the Hash function and the digital signature of a SAODA protocol, adding the concept of fidelity to the middle nodes to serve as the determination basis for their trustworthiness; during the route establishing and data transmitting stage, conducting dynamic calculation and constant updating to the fidelity of the nodes; and when the fidelity reaches a too small point, determining that the node is a black hole node and abandoning it. The method of the invention solves the problem that black hole attacks could not be solved in the existing SAODV protocol. With the method, the black hole node could be identified, therefore, making the network more reliable and more secure. The method is suitable for the Ad-Hoc network.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an SAODV optimization method for effectively resisting black hole attacks, which is suitable for Ad-Hoc self-organizing networks. Background technique [0002] Ad-Hoc (self-organizing network) is a wireless network composed of independent nodes and each node can join, leave and move freely. The topology of its network will change frequently as the state of the nodes changes. In addition, each node in the network has the same possibility of being attacked, so in the Ad-Hoc network, it is necessary to introduce a definite mechanism to prevent malicious attackers from tampering with routing data or discarding data, so as to ensure the security performance of the network. [0003] At present, most Ad-Hoc networks use the on-demand routing protocol—AODV protocol. Each node does not need to maintain accurate routing information, that is, only when the source node wants to send ...
