Focusing on the information security and data communication of UAVs cooperative operation, a data security model for distributed UAV based on blockchain is proposed. A blockchain structure of UAV is reconstructed by using lightweight encryption , and a distributed blockchain network model is designed that suitable for the edge computing scenario of the Internet of things. The smart contract to complete the secure sharing of blockchain data is deployed, and a consensus protocol of work proof is proposed to complete the data transaction that combining with the reputation evaluation scheme and the idea of proxy rights and interests proof. Experimental results show that as an example of data security sharing, the BC_ UAV can reduce the reputation value of the attacked UAV to an untrusted and effectively suppress malicious attacks under different attack modes, while the normal node transaction rate of the consensus algorithm with adaptive workload proof can be increased by 3-4 times, so that the model provides a security guarantee for UAV data sharing.
