Embodiment Construction

[0056] Below the attachment in the embodiments of the invention will be clearly and fully described in the technical solutions in the embodiments of the present invention. Obviously, the embodiment described is only a part of the embodiments of the invention, not all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technical personnel in the art under the premise of not creating creative labor belong to the protection of the present invention.

[0057] In order to certify the safety of nodes in the node group, the embodiments of the present invention provide a node certification method, system and device.

[0058] Examples of the present invention provide a node certification method, which is applied to the first node. The above methods include:

[0059] In the case of receiving the certification request sent by the above second node, the first reputation value of the above -mentioned second node, the first social inten...

Abstract

The embodiment of the invention provides a node authentication method, system and device, relates to the technical field of data processing, and is applied to a first node. A first reputation value of the second node, a first social strength between the second node and the first node, and a first physical distance between the second node and the first node are obtained. And calculating a security value of the second node according to the first reputation value, the first social strength and the first physical distance. And under the condition that the security value meets the preset security requirement, first information representing that the second node passes the authentication is sent to the second node, so that the second node determines that the second node passes the authentication. And under the condition that the security value does not meet the preset security requirement, second information representing that the second node does not pass the authentication is sent to the second node, so that the second node determines that the second node does not pass the authentication. By applying the scheme provided by the embodiment of the invention, the security authentication of the node can be realized.

Description

Technical field [0001] The invention involves the field of data processing technology, especially a node certification method, system and device. Background technique [0002] In some application scenarios, different devices can be used as nodes, each node forms a node group, and data sharing with each other and jointly processing. For example, in the field of transportation, different vehicles can be used as nodes to form a vehicle node group, and data sharing can be performed between each vehicle. For example, the shared data can be used for data for the vehicle location and vehicle speed. Treatment can increase the safety of vehicles. In the field of user credit, the servers of different institutions can be used as nodes, such as banks' servers, shopping platform servers, etc., and each node forms a user credit data processing node group. Data sharing can be performed between servers of each institution. For example, shared data can be: user consumption information, user payme...
