Method for evaluating and authorizing peer-to-peer network node by certificate

Abstract

The invention discloses a method for carrying out evaluation and authorization to nodes in a peer-to-peer network by applying a certificate, which provides a safety-oriented authorization scheme in the peer-to-peer network, takes advantage of the features such as the strong dynamism of the peer-to-peer network and the strong independence of the nodes, etc., adopts the authorization scheme that associates evaluation with permission and essentially solves the problem of safe authorization in distributed computation. The method of the invention comprises the steps that: according to the levels of the authority certificate hold by the nodes and the levels of resources that are asked to be accessed by resource requesters, authorized decision-making is carried out by a resource provider; after transaction is finished, the resource providers and the resource requesters directly adopt the certificate to evaluate the performance of the other party; when a node logs in next time, the obtained evaluation certificate and the left authorization certificates are exchanged on a super node firstly so as to obtain the timestamp of a new certificate, continue the afterwards transaction, and improveevaluation rationality and authorization security carried out to node behavior in the peer-to-peer computing field. Compared with other evaluation and authorization schemes, the scheme of the invention is characterized by simplicity and safety, etc..

Description

technical field [0001] The present invention proposes an authorization scheme that focuses on security in the peer-to-peer network, utilizes the characteristics of peer-to-peer network nodes such as strong dynamics and strong node autonomy, and adopts an authorization scheme associated with evaluation and authority, which is mainly used to solve distributed computing The security authorization problem in , belongs to the field of distributed computing security. Background technique [0002] Peer-to-peer computing is a typical distributed computing technology that can make full use of scattered idle resources at the edge of the network, such as computing power resources, storage resources, and data resources of nodes, to promote resource sharing, cooperative computing, and information interaction. With the continuous improvement of network bandwidth and the rapid development of computer technology, P2P technology is gradually applied to the fields of file sharing, instant mes...

AI Technical Summary

Problems solved by technology

However, there are still some problems

For example, the evaluation algorithm is complicated, the acquisition of historical interaction experience is incomplete, the interaction experience takes up a large storage space, and the interaction experience is easy to be forged, etc.

Failure to use corresponding methods to solve these problems will affect the accuracy of the evaluation results, thereby affecting the security of authorization
