Abstract: In order to break the ‘information island' effect formed by traditional isolated and decentralized systems, and ensure the credibility and security of user-related information in heterogeneous alliance systems, an alliance system user trust negotiation model based on two-layer blockchain is proposed in this paper. The model uses the blockchain technology to protect the user behavior data from tampering, and forms a user behavior data blockchain (ie, the frst layer of blockchain). Based on these behavioral data, the user's trust value can be calculated to form a user trust blockchain (ie, the second layer of blockchain). Through simulation experiments and security analysis, it demonstrates that the user behavior data and trust value cannot be falsifed through the proposed model, as well as the related information can be safely shared in the heterogeneous alliance system.

Key words: heterogeneous alliance systems, two-layer blockchain, trust negotiation, trust evaluation
