Design And Implementation Of Safety Probe System Based On Blockchain

With the rapid development of Internet technology,the quality of network transmission has attracted more and more attention.Therefore,it is very important to master the current network status,topology and network performance.Large-scale network detection platform has become an important tool to understand network performance and network topology,and is used by more and more network service providers.The network measurement platform uses a large number of probes distributed in the network to obtain the operation status of the network.Probes have a strong capability of network detection,if controlled by malicious users,it will have a negative impact on the network.However,in existing probe systems,probes are not able to identify whether the measurement tasks sent by the server are created by real users.If the server is invaded,these probes can be used by hackers.Block chain is a distributed ledger,which can record data reliably and safely,and synchronize data on all nodes.Adding the probe to the block chain network can provide the basis for the probe to distinguish the measurement tasks.This paper designs and implements a security probe system based on block chain.The security probe system proposed in this paper includes chain code module,probe module and server module.Chain code module handles data access and verification logic on block chain to ensure the reliability of data on the chain;probe module verifies and executes measurement tasks;server module handles user requests and signatures users' tasks to ensure that tasks are verifiable.This system can protect probes from attacks such as message tampering and replay attack,and improve the security of probes.In the test,the system is well resistant to these attacks.
