Problems solved by technology

[0005] The purpose of the present invention is to provide a cloud computing platform-oriented ciphertext access control system, aiming at solving the problem that in the existing cloud computing platform adopting the attribute-based encryption scheme, the user's private key is obtained through a fully trusted key generation center to generate and distribute, and cloud service providers cannot be trusted to faithfully implement user-defined access control schemes, which leads to the problem of poor security of access control systems

Abstract

The invention belongs to the technical field of cloud services, and provides a cloud computing platform-oriented ciphertext access control system and an access control method thereof. The system and method aim at the key escrow problem existing in the traditional attribute encryption scheme. The generation of a part of the user's private key is handed over to the authorization center, and the rest of the user's private key generation is handed over to the cloud. The authorization center and the cloud They are independent and cannot collude, thereby ensuring the privacy and confidentiality of user data, ensuring the data security of data owners, and supporting fine-grained access control for visitors, thereby improving the practicability of the cloud computing platform. Safety and reliability.

Description

technical field [0001] The invention belongs to the technical field of cloud services, and in particular relates to a cloud computing platform-oriented ciphertext access control system and an access control method thereof. Background technique [0002] With the development of information technology, cloud computing (Cloud Computing) has become a research hotspot in the field of global information technology and an important opportunity for industrial innovation and development. Cloud computing is a new type of computing model that can more effectively use computing resources to provide users with various data services. It links a large number of computing resources, storage resources and software resources, and uses virtual technology to provide users with customizable Computing, storage and application services, avoiding the construction and maintenance of users' own heavy infrastructure. Cloud computing has attracted more and more attention due to its convenience, economy...
