Embodiment 1

[0063] The inventors of the present application found through a lot of practice that the existing software-defined opportunistic network has security problems, and considering the characteristics of blockchain decentralization, network robustness, safety, reliability, and flexibility, it is very suitable for solving today's Core Flaws in Software-Defined Opportunistic Networking Technologies. The biggest feature of blockchain technology is that it can promote all nodes in the network to reach consensus by combining distributed ledger technology and its unique consensus mechanism in a decentralized environment without any single point of trust. The essence of blockchain is The above is a decentralized chain structure database, using traditional cryptography as a pointer to associate each "block". The present invention analyzes the unique consensus mechanism of the block chain, such as the commonly used workload proof mechanism (PoW, Proof of Work), equity proof mechanism (PoS, ...

Abstract

The invention discloses a software-defined opportunity network node identity verification method based on a block chain, comprising the following steps: firstly, grading each received message by a mobile node, and sending the generated message grading to a corresponding area authentication unit; then, aggregating the received message rating of the mobile node for the same message by a region authentication unit; generating a trust value offset of each message, forming a trust value offset block, selecting a target area authentication unit by adopting a consensus mechanism combining the workload proof and the rights and interests proof, and uploading the formed trust value offset block to a pre-generated public accessible trust block chain. A workload proving mechanism and a miner electionmechanism in a block chain are adopted, a solution for the node identity verification problem in the software-defined opportunity network is provided, the network security can be greatly optimized onthe premise that the original characteristics of the network structure are not changed, and a guarantee is provided for normal internal communication of the software-defined opportunity network.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a blockchain-based software-defined opportunistic network node identity verification method. Background technique [0002] As a new type of network structure, software-defined opportunistic network has the dual characteristics of opportunistic network and software-defined network. First of all, as an opportunistic network, it is a mobile self-organizing network structure that can tolerate structural splits, which is an important difference from traditional networks. The most distinctive features of opportunistic networks are the absence of central nodes, self-organization among mobile nodes, constantly changing network topology, and limited storage capacity and energy of mobile nodes. An opportunistic network contains several different nodes, all of which have a certain range of communication, and have a certain law of motion, and attributes such as mobility models and communi...
