Embodiment Construction

[0068] The present invention will be further elaborated below by describing a preferred specific embodiment in detail in conjunction with the accompanying drawings.

[0069] like figure 1 As shown, it is a flow chart of a multi-Agent transaction information protection method based on block chain technology in the present invention, and the method includes:

[0070] S1. Create accounts for each entity in the multi-agent e-commerce system, and generate account public key and private key information.

[0071] There are seller Agent and buyer Agent on different clients, and buyer management Agent and seller management Agent, and there are server administrators on the Web server. Among them, the buyer's Agent and the seller's Agent are both multi-Agent systems, which use multiple Agents with clear division of labor to perform tasks such as search, decision-making, management, negotiation, and transaction.

[0072] When the user uses the blockchain-based e-commerce platform for th...

Abstract

The invention discloses a multi-Agent transaction information protection method based on a block chain technology. According to the method, a transaction execution platform which only has credible andsafe transaction information protection execution environment is established by utilizing a block chain. A transaction process between the buyer and the seller is realized by using the transaction execution platform. Besides, a BFT-Raft consensus algorithm based on Byzantine fault tolerance is adopted, and the method has the advantages that due to the establishment of a multi-Agent e-commerce system, the transaction cost and the user time can be remarkably reduced, and illegal authorization acquisition, use and leakage of transaction information are effectively prevented. The BFT-Raft consensus algorithm ensures that the log is not tampered by applying a digital signature technology and incremental hash in a log replication link. Through a Committed proving mechanism, it is ensured that aselected Leader node must have all log items reaching consensus, the BFT-Raft consensus algorithm can solve the consensus problem in a Byzantine fault-tolerant environment, the number of nodes participating in verification and accounting is greatly reduced, and second-level consensus verification can be achieved.

Description

technical field [0001] The invention relates to the field of multi-Agent e-commerce information security, in particular to a blockchain-based multi-Agent e-commerce transaction information protection method. Background technique [0002] With the rapid development of the Internet, the explosive growth of business information and the increasingly complex network environment, the traditional e-commerce process and its supporting technologies are facing new challenges, and their defects are becoming more and more obvious. It is almost impossible for customers to search all shopping sites, analyze relevant information and come up with sound decisions. To solve this problem, Mobile Agent is considered as a useful e-commerce solution. [0003] Mobile Agent is an executable program, which can carry its code and state and move from one node to another in the network autonomously, looking for suitable computing resources and information resources, and completing specific tasks. The...
