Book resource access control method based on Chinese remainder theorem

Abstract

The invention provides a book resource access control method based on the Chinese remainder theorem. The book resource access control method comprises the steps that a book resource authentication center and a resource access terminal generate respective public and private key pairs; the resource access terminals interact with the book resource authentication center to perform attribute identity authentication, and each resource access terminal sends attribute parameters to the book resource authentication center, verifies the attribute parameters and sends the attribute parameters to the resource storage platform; the resource access terminal encrypts the shared resource information into a ciphertext and uploads the ciphertext to the resource storage platform; and the resource access terminal determines a ciphertext resource to be checked according to the ciphertext, the resource storage platform verifies the identity of the ciphertext resource and opens an access link of the ciphertext resource, and the resource access terminal downloads the ciphertext for decryption. Personal privacy is protected by adopting ciphertext attribute authentication, access permission is set by applying an attribute matching access control strategy to guarantee safety of resource sharing, collusion attacks are prevented by adopting identity and attribute permission dual authentication, and book resource sharing in the Internet of Things is more flexible, efficient and practical.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a book resource access control method based on the Chinese remainder theorem. Background technique [0002] The rapid development and continuous innovation of computer technology and the Internet of Things have improved the efficiency of information storage and real-time exchange. But the ensuing computer information security issues are also increasingly revealed, and more and more people pay more attention to information security issues while enjoying the convenience. Access control is one of the cornerstone technologies of data information protection, which can ensure that data can only be accessed by users with corresponding permissions. Set access control policies to divide access rights, obtain information access rights through attribute parameter matching, and use different attribute parameters to access data information with different degrees of sensitivity, ...

Problems solved by technology

[0005]In the process of identity authentication for existing information resource sharing methods, personal identity information is easily exposed, sensitive data cannot be flexibly protected, and access rights of resource access terminals in the domain cannot be determined To solve the technical problem, the present invention proposes an access control method based on the Chinese remainder theorem, which adopts identity authentication technology with hidden attributes to realize identity authentication in the identity authentication process of resource information sharing while protecting personal privacy well, and adopts Attribute parameter matching divides access rights technology, which reduces the calculation and communication overhead of each participant, adopts joint authentication of identity and attribute rights, and avoids collusion attacks by terminals without rights
