Embodiment Construction

[0055] For the convenience of description, we assume the following application examples: Assume that the autonomous area A is adjacent to the autonomous area B, and there are state nodes D and E in the autonomous area A, where D is the main state node, E is the non-main state node, and the ordinary node F, G; There are state nodes H and I in the autonomous area B, where H is the main state node, I is the non-main state node, and ordinary nodes J and K.

[0056] 1: Trust the workflow of data storage:

[0057] Step 1: Ordinary node F in autonomous area A requests a transaction with ordinary node J in autonomous area B.

[0058] Step 2: After the transaction, node F evaluates node J according to the service quality provided by the node, and the evaluation result is saved in the local (node ​​F) transaction record table.

[0059] Step 3: After the transaction record table is updated, node F updates the local trust value of node J in the table according to the evaluation records o...

Abstract

The invention relates to a trust data management method in a peer-to-peer network, which provides a safer, available and highly efficient trust data management mechanism for solving the problem of some defects exiting in a traditional data management mode. Differing from past pure centralized type and scattered type management mechanisms, the centralized type and the scattered type are effectively combined by the management mechanism and mutually make up for deficiencies. The equilibrium, the safety and the high efficiency of data access can be achieved by using the trust data management mechanism disclosed by the invention. The method is a method that the centralized type and the scattered type are effectively combined, mutually make up for deficiencies and are improved, and two nodes logically exist in the network. One is a state node which is used for managing a trading state table; and the other is an ordinary node which is a basic element for forming the network and is used for storing a trading record table per se. Trust data management can be safely and efficiently realized by quoting the trading state table and the trading record table.

Description

technical field [0001] The present invention is an open network environment, which is mainly used to solve the trust data management problem of the trust model in the P2P network. This method provides a more secure, usable and efficient management mechanism, which belongs to the network peer-to-peer computing and resource management Cross-application areas of technology. Background technique [0002] Because the P2P network has the advantages of dynamics, self-organization, good scalability, good scalability, and strong adaptability, after years of research and development, P2P is widely used in various fields, such as file sharing, instant messaging, network collaboration, etc. . .But at the same time, due to the open and dynamic nature of the P2P system, a large number of malicious acts such as fraud and forgery seriously affect the availability of the system, making the P2P system both benefits and risks. In order to ensure the security, fairness, and reliability of the...
