The present application relates to a kind of multi-node probe flexible attachment re-planning method, belong to aerospace and artificial intelligence cross technical field.The system constraint conflict problem that may be generated by the task sequence of initial planning being executed in view of small asteroid exploration activities, due to insufficient cognition to small asteroid environment, each node of probe and possible fault in node subsystem, facing the flexible attachment task demand of multi-node probe, the present application establishes the flexible landing re-planning problem model of multi-node probe, creates the layered constraint graph model of re-planning, proposes the re-planning method of layered time delay satisfaction verification mechanism and layered neighborhood re-planning search algorithm based on layered constraint graph, to meet the demand of multi-node probe flexible landing to autonomous re-planning.The present application lays a technical foundation for the successful landing of multi-node probe and subsequent small asteroid resource collection, planet walk and other further exploration tasks.

The application relates to a kind of implementation methods of verifiable Internet of Things device data asset transaction, based on the data seller, blockchain and data buyer involved in Internet of Things data asset transaction system, the process for realizing verifiable data asset transaction is as follows: data seller publishes encrypted data on blockchain through smart contract, data buyer requests data according to needs and submits verification request.Smart contract is responsible for verifying the integrity and authenticity of data, and transmits decryption key to data buyer after verification.The data buyer decrypts the data using the key and completes the transaction.If the buyer finds that the decrypted data is abnormal, the smart contract is called to initiate arbitration.Through the confusion encryption mode, RSA accumulator technology, hash verification mechanism and on-chain arbitration mechanism, these attack behaviors are effectively resisted, and the privacy, integrity and verifiability of data transaction are ensured.
