Embodiment Construction

[0036] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0037] At present, the mobile crowd sensing network can greatly enrich the functions of people. As independent individuals in society, people will not only use the perception data in the network, but also actively "produce" data and upload it to the network for other users to use. Users start as the main body of data perception, collection, analysis and mining, complete the whole process spontaneously, and then complete the perception tasks published on the network. However, when many users share perception data in order to cooperate to complete the same task, they need to cooperate with each other, that is, node authentication.

[0038] In the traditional node authentica...

Abstract

The invention provides a node authentication method and device based on a non-interactive zero-knowledge proof, and the method comprises the steps: setting a registration party between a requesting party and a verification party as a third party trusted mechanism; enabling the registration party to perform the information generation and transmission in an authentication process between the requesting party and the verification party, and enabling the requesting party and the verification party not to perform the information interaction in the whole node authentication process besides that theverification part is informed of whether the authentication of the requesting party is successful or not. Therefore, any secret information of the requesting party cannot be leaked, so as to achieve the high confidentiality of the privacy information of the requesting party. Moreover, the requesting party and the verification party do not need to perform the information interaction for many timesfor the successful authentication, thereby improving the efficiency of node authentication and the user experience.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a node authentication method and device based on non-interactive zero-knowledge proof. Background technique [0002] As an emerging product in the era of big data, the mobile crowd sensing network can greatly enrich the functions of people. As independent individuals in society, people will not only use the perception data in the network, but will actively "produce" data and upload it to the network. In order to be used by other users, users start as the main body of data perception, collection, analysis and mining, and complete the whole process spontaneously, and then complete the perception tasks published on the network. With the popularization of mobile terminal equipment, mobile crowd sensing network has begun to have a wide range of applications and has penetrated into all aspects of social life, such as environmental pollution-free quality monitoring, intelligen...
