Abstract:

In view of the abuse of power by managers in the traditional centralized trading system, a security model without managers for the blockchain-based trading system was proposed, which also solved the problems of unsafe endorsement, untimely trading, low auditing efficiency and dynamic inefficiency caused by the elimination of managers.The proposed security model realized decentralization based on the blockchain technology, by using homomorphic authentication-based public auditing to achieve the secure endorsement and key updating for non-manager groups and efficient verification for transaction information respectively, introducing the reputation-based incentive mechanism to ensure the timeliness of the transaction.Finally, the security and reliability of the proposed security model were demonstrated by security proof and performance analysis, and the communication and computing costs are both lower than IPANM.

Key words: blockchain, trading system, security model
