Multi-mobile device authentication method for underwater acoustic collaborative network based on blockchain technology

Abstract

An authentication method for multiple mobile devices in an underwater acoustic collaborative network based on blockchain technology, involving an underwater acoustic network. Introduce blockchain technology into the marine Internet of Things based on the underwater acoustic network. According to the time consumption model of underwater acoustic data transmission, a multi-mobile device authentication method based on the cooperation of the primary and secondary cluster heads is proposed. It takes a certain amount of blockchain consensus time, but when the peripheral mobile device moves to another cluster and requests to re-connect to the network, the primary and secondary cluster heads of other clusters do not need to re-identify them after checking on the public ledger of the blockchain Verification, save the identity verification time of network access. The primary and secondary cluster head cooperation scheme makes it possible for the primary and secondary cluster heads to perform initial identity verification and account check on two peripheral mobile devices at the same time after receiving the identity verification request when there is a secondary cluster head. In this case, more time is saved, and the authentication delay for underwater mobile devices to request network access is significantly reduced.

Description

technical field [0001] The invention relates to an underwater acoustic network, in particular to a method for verifying the identity of multiple mobile devices in an underwater acoustic collaborative network based on block chain technology. Background technique [0002] With the development and maturity of Internet of Things technology, in order to alleviate the shortage of resources faced by the development of human society on land, people began to explore and develop the Internet of Things in the ocean to develop marine resources with rich reserves and great potential. At present, due to the particularity of the underwater environment, underwater acoustic communication technology is the key to successfully connecting underwater Internet of Things (IoUT) devices to the Marine Internet of Things, and has important application prospects in both civilian and military fields. [0003] In the marine Internet of Things composed of IoUT devices, it is often necessary to use AUV an...

Problems solved by technology

[0005] However, in the above method, only one main cluster head is set in each cluster of the marine Internet of Things to authenticate the peripheral underwater mobile devices to access the network, and each time only a single mobile device requests to enter the cluster for networking, and multiple cluster heads are not considered. The identity verification problem of peripheral mobile devices requesting to enter the cluster for networking at the same time cannot meet the new development and application requirements of high data throughput and multi-task parallel operation of the future marine Internet of Things

[0006] At present, it is rare to use blockchain technology in the marine Internet of Things to design and research related underwater acoustic networks.

In addition, the uncertainty of the network topology of the IoUT device cluster in the marine Internet of Things has brought great challenges to the security design of the underwater acoustic network. How to use blockchain technology for design has a certain degree of foresight
