Embodiment Construction

[0021] Such as figure 1 As shown, a trust chain-based underwater mobile node re-authentication method includes the following steps:

[0022] (1) The cluster head broadcasts periodically to check whether the member nodes have left the communication range of the node;

[0023] (2) ctr is a special character string specified by the cluster head for broadcast query, and the cluster head broadcast ciphertext M 0 , member nodes receive M 0 A response message M will be generated 1 And send it to the cluster head, after receiving the response from the member nodes, the cluster head thinks that the node is still in the communication coverage area of ​​the cluster at this time; once the cluster head does not receive the feedback from the member nodes, the cluster head thinks that the node has moved ;

[0024] (3) The member node has moved and left the communication range of the cluster head. At this time, the cluster head will send a message to its neighbor cluster head to notify th...

Abstract

The invention discloses a trust chain-based underwater mobile node re-authentication method, which includes the following steps: the cluster head broadcasts periodically, and inquires whether the member nodes have left the communication range of the node; the cluster head broadcasts ciphertext, and the member nodes A response message M is received 1 And send it to the cluster head. After receiving the response from the member nodes, the cluster head thinks that the node is still in the communication coverage area of ​​the cluster at this time. Once the cluster head does not receive the feedback from the member nodes, the cluster head thinks that the node has moved ;The member node has moved and left the communication range of the cluster head. At this time, the cluster head will send a message to its neighbor cluster head, and distribute the key information for the re-authentication of the mobile node to the neighbor cluster head; the new cluster head 3 receives After receiving the message M and broadcasting the ciphertext M, the original cluster head 2 will delete all information related to the mobile node in the memory. The invention solves the problems of higher calculation complexity, higher communication overhead and storage overhead of underwater mobile node re-authentication.

Description

technical field [0001] The invention relates to the technical field of authentication protocols, in particular to a trust chain-based underwater mobile node re-authentication method. Background technique [0002] Abundant marine resources and a large number of marine application scenarios have made researchers around the world increasingly keen on the development of marine resources and the research on underwater acoustic communication network technology. Scientific researchers around the world are more widely involved in marine technology research, and countries are paying more and more attention to the acquisition and processing of marine information. Ocean data is the key basis for all ocean technology applications, including data generation, collection, storage, transmission, and processing. Therefore, key technologies of underwater acoustic communication networks have gradually become key research topics for major oceanic countries. Designing and developing a low-cost,...
